    Linear and networked poly(ionic liquid)s, which were composed of polyoxetanes and imidazolium groups, were synthesized by cationic polymerization of mono- and di- functional oxetanyl monomers, and the properties of the obtained polymers were investigated. The monofunctional monomer, 3-(3-ethyl-3-oxetanylmethyl)-1,2-dimethylimidazolium bis(trifluoromethanesulfonyl)imide (OXDMImTFSI), was prepared from the reaction of 3-ethyl-3-oxetanylmethyl chloride with 1,2-dimethylimidazole followed by exchanging the chloride to bis(trifluonomethanesulfonyl)imide (TFSI). The difunctional monomer, 1,3-di(3-ethyl-3-oxetanylmethyl)-2-methylimidazolium bis(trifluoromethanesulfonyl)imide (DOXMImTFSI), was prepared from the reaction of 3-ethyl-3-oxetanylmethyl chloride with 2-methylimidazole and successive ion-exchange of chloride to TFSI. OXDMImTFSI was polymerized by addition of a catalytic amount of BF3 diethyl ether complex. The obtained linear polyOXDMImTFSI showed good stability toward heat and basic conditions. Networked polymer films were prepared by homo/co-polymerization of DOXMImTFSI or DOXMImTFSI/OXDMImTFSI liquid layers using the thermally latent cationic initiator, (1-naphthylmethyl) methyl p-hydroxyphenyl sulfonium hexafluoroantimonate (SI-60). The obtained films showed good ion-exchange ability between TFSI, Cl, and OH anions.

    Dopamine-modified carboxymethyl cellulose (DOPA-CMC)s with various degrees of DOPA substitution (DS)( 7~9%) were synthesized, and their solution behaviors and adhesion properties toward pig skin were investigated under various conditions. DOPA-CMC(DS9%) in phosphate buffer solutions (PBS, pH6.0, pH7.0, pH8.0) was a colorless liquid, while its solution in trishydroxymethylanimomethane buffer solution (Tris, pH8.0) changed to a brown gel. The polymer solution was applied to a pig skin strip and adhered to another strip by crimping and drying for 24 h. Then the tensile strength of the sample was measured; this value was evaluated as dry adhesion strength. An analogously prepared sample was further immersed in water for 1 h and the tensile strength was measured; this value was evaluated as wet adhesion strength. The dry adhesion strengths of the PBS (pH6.0~8.0) solutions were high and almost constant at 0.71 MPa ~ 0.53 MPa, while the wet adhesion strengths remained low at 0.04 MPa ~ 0.07 MPa. The dry adhesion strength of Tris(pH8.0) solution was 0.63 MPa, which was almost the same as that of the other PBS solutions, but its wet adhesion strength rose to 0.16MPa, which was significantly higher than those of the other solutions. This high wet adhesion strength of the Tris solution was supposed to be caused by the crosslink of the DOPA-CMC due to the oxidative coupling of the DOPA groups. We also found that composite materials prepared by mixing DOPA-CMC(DS7%) and monomeric dopamine with Tris buffer solution showed higher wet adhesion strength than that prepared by mixing DOPA-CMC with only theTris buffer solution.

    Networked polymers were synthesized by crosslinking a polycarbosilane having acetylglucosamine-derived groups (AGA) on the side chains (polyBMSB-AGA) with hexamethylenediisocyanate (HMDI) and their chemical and physical properties were investigated. Two networked polymer films (polyBMSB-AGA-HMDI-1.0 and polyBMSB-AGA-HMDI-0.5) were prepared by adding HMDI to polyBMSB-AGA in molar ratios of [AGA] / [HMDI] = 1.0 and 0.5 respectively, and their N,N-dimethylformamide (DMF) solutions were cast on the Teflon mold followed by heating up to 120 oC. Existence of urethane structures in the materials was confirmed by IR spectroscopy. Differential scanning calorimetry analysis (DSC) indicated that the crystallization of AGA groups was inhibited in the crosslinked polymer. Thermal gravimetric analysis (TGA) suggested that the networked polymers were thermally stable below 140 oC. In addition, tensile strength analysis showed that the polyBMSB-AGA-HMDI-0.5 film had breaking strength of 155MPa and breaking elongation of 0.16, which indicated that the networked polymer was significantly tough material, compared to the previously reported analogous networked materials (polyBMSB-Glucose-HMDI-0.5) composed of polycarbosilane having glucose-derived groups crosslinked with HMDI.

    Two polybenzimidazole-derived cationic polymers were synthesized, and their chemical and physical properties were investigated to develop hydroxide ion conducting materials for anion exchange polymer membrane fuel cells (AEMFC). One was poly(methylbenzoimidazolium iodide) (PBI-E-3.8MI), which was synthesized by N-methylation of polybenzoimidazole having ether oxygen (PBI-E). The other was polybenzoimidaozole having propytrimethylammonium bromide groups (PBI-DB-1.4TAB), which was synthesized by introduction of propyltrimethylammonium groups on the imidazole nitrogen. PBI-E-3.8MI showed high thermal stability but low alkaline resistance with low anion exchange ability. On the other hand, PBI-DB-1.4TAB exhibited moderate thermal stability but high alkaline resistance with high anion exchange ability. PBI-DB-1.4TAB film also showed good ionic conductivity under alkaline conditions along with a good mechanical strength. These results suggested that PBI-DB-1.4TAB can be a good candidate as hydroxide ion conducting materials for AEMFC.

    A polycarbosilane having lactose-derived structures was synthesized, and its thermal property, cytotoxicity, chemical crosslinking, and protein adsorption properties were investigated. The polycarbosilane (PSB-Lac) was prepared by a thiol-ene reaction between precursor poly(1-(3-butenyl)-1-methylsilacyclubane) (PSB) and heptaacetyl lactose that carried a thiol group at the anomeric position, and the successive deprotection of the acetyl groups. The lactose introduction efficiency determined by 1H NMR measurement was 75%. Thermal gravimetric analysis (TGA) and differential scanning calorimetry (DSC) revealed that the polymer had a 5 wt% decomposition temperature of 260 oC and glass transition temperature (Tg) of 84 oC, which indicated that PSB-Lac was a thermally stable polymer. PSB-Lac had no significant cytotoxicity, which was evaluated by human liver cancer cell line HepG2 cultivation on the polystyrene dishes coated with the polymer. Urethane-crosslinked PSB-Lac films were prepared by casting solutions of PSB-Lac and hexamethylene diisocyanate and heating at 120 oC after evaporation of the solvent. The crosslinked PSB-Lac showed higher adsorption of bovine serum albumin (BSA) than the similarly crosslinked polycarbosilane that had a glucose structure (PSB-Glc).

    Hyperbranched polyacetals (HBPAs) bearing cyclic carbonate (CC) terminals were synthesized from protocatechuric aldehydes bearing bifunctional trimethylolpropane (TMP) or glycerol (Gly) structures and then utilized to design polymer electrolytes and networked polymer materials. Since TMP-based cyclic acetals (CAs) are thermodynamically more stable than Gly-derived CSs, the copolymerization of these monomers favors to form HBPAs comprising TMP-based acetal stems and Gly terminals. Consequently, HBPAs composed of larger amounts of TMP or Gly terminals were separately synthesized by changing monomer feed ratios. Their diol terminals react efficiently with diphenyl carbonate to give HBPAs bearing 5- or 6-membered CC (5-CC or 6-CC) terminals. HBPAs bearing 5-CC terminals were mixed homogeneously with lithium bis(trifluoromethanesulfonyl)imide to form uniform films showing lithium ion conductivity ranging from 8.2 × 10−9 to 2.1 × 10−3 S cm−1 at 23–80 C, whereas networked polycarbonate and polyhydroxyurethane films were successfully fabricated using HBPAs having CC terminals. These results apparently indicate that HBPAs having CC terminals are useful scaffolds to design functional polymer materials.

    Block copolymers containing polytetrahydrofuran segments were synthesized by umpolung or propagating end of the cationic living polymer and successive anionic polymerization of methacrylates (RMAs) or radical polymerization of RMAs, acrylonitrile (AN), and styrene (St). Living polytetrahydrofuran (poly-THF) was prepared by cationic polymerization of tetrahydrofuran (THF), whose propagation end was reduced by samarium(II) iodide ( SmI2). Anionic polymerizations of RMAs were conducted by addition of the monomers to the reduced poly-THF to obtain poly(THF-b-RMAs). On the other hand, the 2-bromoisobutyrate group, which can act as an initiator of radical polymerization, was introduced to the cationic propagating end of poly-THF by adding sodium 2-bromoisobutyrate. Block copolymers were synthesized by living radical polymerization of RMAs, St, or AN using the 2-bromoisobutyrate- capped poly-THF as a macroinitiator and copper(I) bromide (CuBr) as a catalyst.

    In this paper, we report synthesis of DBU derivatives bearing various alkyl substituent (Alkyl DBU)s at 6-position and their catalytic effect in the thermal curing of bisphenol A diglycidyl ether (DGEBA). In the case of DBU, the curing process showed small exothermic peaks at 55 ºC and at 100 ºC. In contrast, in the case of Alkyl DBUs, the curing process exhibited their first exothermic peaks at 125 ºC, and second peaks at 200 ºC. All the cured epoxy resin prepared by DBU derivatives were insoluble, transparent, and hard solids. Compared to the epoxy resin cured by DBU, the resins cured by the alkylated DBUs showed higher gel fraction, volume shrinkage, and heat resistance. Therefore, Alkyl DBUs are expected to be useful compounds as thermally latent and highly active curing agents for epoxy resins.

    Polymers having a zwitterionic pendant group have found a wide range of applications such as fungicides, fire-retardants, lubricating oil additives, emulsifiers, cryoprotectants, and electronic materials. Their properties depend not only on the polymer main chains but also on the zwitterionic structures. In this article, the synthesis of novel polymers having zwitterionic structures is described. A zwitterionic monomer (4-vinylphenyl isothiocyanate [VPI]-1,2-dimetyl-1,4,5,6,-tetrahydropirimidine [DMTHP]) was synthesized by the reaction of VPI and a cyclic amidine DMTHP. A radical polymerization of VPI-DMTHP was carried out using 2,2′-azobis(2,4-dimethyl-4-methoxy)valeronitrile (V-70) as an initiator to give poly(VPI-DMTHP). The obtained poly(VPI-DMTHP) was not soluble in any of the investigated organic solvents, probably because it had a networked structure resulting from the ionic interactions. Copolymers of VPI-DMTHP and other vinyl monomers such as styrene, methyl methacrylate, t-butyl methacrylate, and N-vinylpyrrolidone were synthesized. The obtained copolymers were also insoluble in all of the examined common organic solvents even when the VPI-DMTHP content was low (5 mol %), indicating the existence of strong ionic interactions in the zwitterionic moieties. © 2018 Wiley Periodicals, Inc.

    Poly(γ-glutamic acid)s (DTC-γPGAs) having 5-Membered cyclic dithiocarbonate structures were synthesized, and their crosslinking along with adhesion property of the obtained materials were examined. DTC-γPGAs were prepared by addition of 5-hydroxymethyl-1,3-oxathiorane-2-thione (DTC-OH) to a dimethyl sulfoxide (DMSO) solution of γPGA in the presence of 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide. Crosslinking of DTC-γPGAs was conducted by addition of 4,7,10-trioxa-1,13-tridecanediamine (TODA) as a crosslinker to an ethanol suspension leading gel formation. The polymer gels produced were cross-linked with thiourethane-linkage. Adhesion strengths were measured by coating the gels between two pieces of pig skin strip and bind together. Examination with varying TODA amount, DTC modification ratio, binding time revealed that DTC-γPGA (34/66) with 0.25 equivalent of TODA showed high T-type peering adhesion strength of 800N/m after 24 h binding.

    Abstract: Networked polycarbosilanes having glucose groups were synthesized and their physicochemical properties were investigated. Film-shaped polysilacyclobutane having glucose pendant groups was crosslinked by thermal urethane formation with a crosslinker, hexamethylene diisocyanate (HMDI). Several films were prepared by varying the feed ratio of [Glucose]/[HMDI]. Thermal stability, phase transitions, mechanical strength, and water absorption were examined by thermal gravimetric analysis, differential scanning calorimetry, tensile tests, and immersion swelling in water. We found that the networked polycarbosilanes having glucose groups were thermally stable, flexible, and tough materials with moderate hydrophilicity, which depends on the urethane crosslinking density. Graphical abstract: Networked polycarbosilanes having glucose groups were synthesized and their physical properties were investigated. Film-shaped polysilacyclobutane having glucose pendant groups was crosslinked through urethane formation by heating with a cross-linker, hexamethylene diisocyanate. We found that they were thermally stable, flexible, and tough materials with moderate hydrophilicity.

    The title polysiloxane was prepared by polycondensation of 2-(1,3-dioxolan-2-only)ethyldimethoxymethylsilane. Ionic conductivity of the polymer was measured after addition of lithium trifluoromethanesulfonate (LiOTf) or lithium bis(trifluoromethanesulfonyl)imide (LiTFSI). In the case of LiOTf, the maximum value of ionic conductivity was reached when 2.0 equivalents of LiOTf per carbonate group were added, but the value was rather low (3.6 X 10-8 S/cm at 30°C). In the case of LiTFSI, on the other hand, the conductivity increased with the increase of LiTFSI amount, and it reached 7.7 X 10-5S/cm at 30°C when 4.0 equivalents of LiTFSI were added.

    Polymerization promotors of benzoxazine-alicyclic epoxy resin mixtures were investigated aiming to achieve their complete curing at 150 ℃ within 3 hours, and their polymerization bahaviors and thermal properties of the cured materials were examined. As a result, it was found that addition of 0.1mol% Tb(OTf)3 lowered the polymerization temperature about 20 ℃ and exhibited the maximum promotion effect on the benzoxazine polymerization at 150 ℃ for 3 hours.

    Various arylmethylpyridinium tetrakis(pentafluorophenyl)borates were synthesized and their properties as cationic thermally-latent curing agents for epoxy resins were studied. Arylmethylpyridinium chlorides were prepared by reaction of arylmethylchlorides with cyanopyridines. The desired arylmethylpridinium borates were obtained by the successive ionexchange of these salts with sodium tetrakis(pentafluorophenyl)borate. Catalytic activity of the pyridinium borates toward bisphenol A diglycidyl ether (BAGE) and difunctional alicyclic epoxy resin (Celoxide) were examined by differential scanning calorimetry (DSC). Storage stability of the epoxy resins/salt mixture at room temperature for one month was examined by 1H-NMR measurements. We found that p-methoxybenzyl-3-cyanopyridimium tetrakis(pentafluorophenyl) borate (pMB3CPB) has high curing activity with good storage stability toward epoxy resins. We also found that the cured BAGE possessed higher glass transition temperatures and higher adhesion strength to stainless steel than the resin cured with a conventional sulfonium antimonate.

    New polyesters bearing a carbosilane repeating unit (-C-Si(CH3)(2)-C-), 1a and 1b, and reference polyesters with the corresponding carbon-based units 2a and 2b were synthesized and evaluated to study the effect of the carbosilane segment on their thermal properties. DSC analysis revealed that 1a and 1b exhibited glass transition temperatures (T-g) of -72.6 and 11.6 A degrees C, respectively, which were lower than those of 2a and 2b (-53.2 A degrees C for 2a and 63.6 A degrees C for 2b), indicating that the substitution of carbon atoms on polyester backbone with silicone atoms is effective method to change the T-g of polyesters. Furthermore, 1a and 1b showed good thermal stability (T (d5) = 304 A degrees C for 1a and 309 A degrees C for 2a). These results indicate that carbosilane segment may be a promising soft segment for developing new polyester-based materials.

    We report the synthesis of networked polymers based on the radical ring-opening polymerization of vinyloxiranes. First, the radical ring-opening polymerization of monofunctional 2-phenyl-3-vinyloxirane was investigated. Then, we synthesized di- and trifunctional vinyloxiranes and examined the networked polymer synthesis via the radical ring-opening homopolymerization or copolymerization of these monomers. The obtained networked polymers contained vinyl ether structures in the main chain, which was confirmed by infrared analysis. In addition, we examined the radical ring-opening copolymerization of difunctional vinyloxirane and monofunctional vinyloxirane or adamantane-substituted vinylcyclopropane. Thermal gravimetric analysis revealed that the network formation increased their thermal stabilities.

    We conducted ring-opening polymerization of silacyclobutane monomers 1-[2-(2,4-dioxa-3-pentanoyl)ethyl]-1-methylsilacyclobutane (SBMC) and 1,1-di[2-(2,4-dioxa-3-pentanoyl)ethyl]silacydobutane (SBDC) to obtain polySBMC and polySBDC, respectively, and measured their ionic conductivity with addition of lithium bis(trifluoromethanesulfonyl)imide (LiTFSI) or lithium trifluoromethanesulfonate (LiOTf). The ionic conductivity of both polySBMC and polySBDC increased with the increase in the amount of LiTFSI added. The ionic conductivity of polySBMC decreased with the increase in the amount of LiTOf, and that of polySBDC decreased after an increase. PolySBMC and polySBDC showed ionic conductivity of 6.1 x 10(-5) and 1.5 x 10(-4) S/cm at 3 degrees C, respectively, after the addition of 4 mol equiv of LiTFSI per cyclic carbonate. Differential scanning, calorimetry analysis of the polymer revealed that the polymers with a high LiTFSI content formed a crystalline phase around room temperature, but the glass transition temperatures of the amorphous phases were kept low. Infrared analysis suggested the existence of a strong interaction between carbonate carbonyl groups and lithium cations.

    Binary mixture materials were prepared by mixing cross-linked polystyrene and liquid polybutadiene by several methods and their shapes and thermal phase transition behaviors were examined. Evaporating dichloromethane of crosslinked polystyrene and polybutadiene (1/1 wt/wt) solution in dichloromethane at 40 ℃ under reduced pressure gave solid/liquid two-phase-separated materials. Differential scanning calorimetry (DSC) of the materials showed that they had two glass transition temperature (Tg)s, one was Tg(-91.0 ℃) attributed to polybutadiene and the other was Tg (103.1 ℃) attributed to polystyrene. They coincided well with those of original polybutadiene and cross-linked polystyrene, respectively. On the other hand, freeze-drying of the cross-linked polystyrene and polybutadiene (1/1 wt/wt) solution in 1,4-dioxane gave powdered solid materials. DSC analysis of these materials revealed higher temperature shift of polybutadiene Tg (-88.8 ℃) along with lower temperature shift of polystyrene Tg (97.8 ℃). These observations indicated that binary materials with quite different shapes and properties can be prepared by varying the mixing methods.

    Two diglycidyl ethers which consist of a flexible carbosilane segments and of rigid phenylene moieties (1 and 2) were synthesized and investigated in order to evaluate their heat-curing behavior (epoxy homopolymerization) as well as thermal and mechanical properties of the networked polymers. Differential scanning calorimetry (DSC) analysis revealed that melting points of both diepoxides were -73.9 and -50.7 degrees C, respectively. Networked polymers of 1 and 2 showed glass transition temperature (T-g) s below ambient temperature of 2.2 and 18.7 degrees C, respectively. High thermal stability of cured 1 and 2 were confirmed by thermogravimetric analysis (TGA) (5% weight loss temperature (T-d5) = 369 degrees C for 1 and 351 degrees C for 2). Tensile tests of cured 1 and 2 clarified that their Young's moduli were (9.76 +/- 0.135)(-2) and (1.29 +/- 0.114)(-1) MPa, respectively. (C) 2016 Elsevier Ltd. All rights reserved.

    In this paper, we report hemithioketal formation of diphenylpropanetrione (DPPT) with thiols and their recovery. Addition of thiols to the central carbonyl group occurred readily at ambient temperature to provide the thiol adducts of DPPT (DPPT-thiols), which has a hemithioketal structure. On the other hand, oxidizing DPPT-thiols with an oxidation reagent enabled successful recovery of DPPT, which indicated the reversible nature of this system. (C) 2016 Elsevier Ltd.

    A mercapto group generated by addition of 5-phenoxymethyl-1,3-oxathiolane-2-thione and benzylamine could react with cyclic acid anhydrides to give the corresponding carboxylic acids. This method was applied to a polymer modification. Poly(thiourethane)s containing mercapto groups were prepared from difunctional five-membered cyclic dithiocarbonates and diamines could react with succinic or glutaric anhydride to give the corresponding poly(thiourethane)s bearing carboxyl group in the side chains in high yield. Thermal properties of the obtained polymers were examined by thermal gravimetric analysis (TGA) and differential scanning calorimetry (DSC). The obtained polymers showed 5 % weight loss temperatures (T (d5)) at 170 and 216 A degrees C. These polymers exhibited glass transition temperatures (T (g)) at 52 and 57 A degrees C, respectively. Furthermore, a cross-linked poly(thiourethane) was readily obtained using difunctional cyclic acid anhydride, 1,2,3,4-butanetetracarboxylic dianhydride as a cross linker.

    Novel poly(spiroorthocarbonate)s [poly(SOC)]s having a Cardo or bent structure were synthesized by polycondensation of several bis-catechols having fluorene (BCFL), spirobisindane (BCSPI), or spirobischromane (BCSPC) in the structure with 2,2,6,6-tetrachlorobenzo[1,2-d:4,5-d']bis[1,3]dioxole (4ClBD). Synthesis of poly(SOC)s was confirmed by NMR and IR spectrometry. The poly(SOC)s obtained from BCFL or BCSPC were soluble in common organic solvents. The glass transition temperature of the poly(SOC)s was not detected by differential scanning calorimetry (DSC) in the range of 50-300 degrees C. The 10 wt % decomposition temperature of the poly(SOC) s was found to be above 400 degrees C. These results indicated the high thermal stability of the poly(SOC)s. Soluble poly(SOC) s could be possessed to form a film on a glass plate by the spin coat method. The obtained polymer films were 0.2 mu m in thickness with 95% light transmission in the optical wavelength range. These results suggested that the Cardo or bent structure may block the packing of the main-chain of the structure, which improves the solubility of the polymers, increases transparency, and enhances the thermal stability of SOCs.

    Poly(hydroxyurethane) was synthesized by polyaddition of difunctional alicyclic carbonate (DCHC) and m-xylylenediamine (mXDA), and its oxygen transmittance rate was examined. DCHC was prepared from industrially available difunctional alicyclic epoxide, 3',4'-epoxycyclohexylmethyl 3,4-epoxycyclohexane carboxylate (CEL2021P), by insertion of carbon dioxide using N-methyltetrahydroprimidine as a promoter and tetrabutylammonium bromide as a catalyst. Poly(hydroxyurethane), poly(DCHC-mXDA) (M (n) = 2600, M (w) = 5700 GPC relative to polystyrene standards), was obtained by heating DCHC and mXDA in N,N-dimethylacetamide at 100 A degrees C. The obtained polymer was thermally stable up to 220 A degrees C, and exhibited good processability in film preparation. The oxygen transmission rate of the polymer was found to be 127 cm(3)/m(2) day atm at 5 mu m film thickness laminated with polypropylene films, indicating its relatively high gas barrier property. Polyhydroxyurethane was synthesized by polyaddition of difunctional alicyclic carbonate (DCHC) and m-xylylenediamine (mXDA) and its oxygen transmission rate was examined. We found that the polymer possess high gas barrier property. [GRAPHICS]

    In this article, we report a novel reversible crosslinking-decrosslinking system consisting of a polymer bearing vicinal tricarbonyl moieties in its side chains and poly(ethylene glycol) (PEG). A mixture of the tricarbonyl polymer and PEG (0.1 equiv of OH groups relative to the vicinal tricarbonyl moieties) in CH2Cl2 spontaneously turned into an orange-colored gel, in which a network structure was formed through hemiketal linkages. Conversely, the resulting networked polymer could be decrosslinked by treatment with water-containing solvent to recover the linear vicinal tricarbonyl polymer as its hydrate in 90 % yield. Following dehydration process by heating at 100 degrees C under reduced pressure regenerated the original vicinal tricarbonyl polymer.

    Novel polyurethanes bearing carbosilane segments (1a-c) were synthesized. Their thermal and mechanical properties were compared with corresponding reference polyurethanes bearing carbon-based backbone (2a-c). The thermal properties of these polyurethanes were investigated by DSC and TGA. Glass transition temperature was significantly reduced by substituting carbon atom with silicon (1a-c). Moreover, the thermal decomposition temperature of 1a-c was found to be comparable to 2a-c. Furthermore, Young's moduli of 1a-c were lower than those of 2a-c. A large potential of carbosilane unit as a soft segment for building new polyurethanes have been demonstrated in this paper.

    Polycarbosilanes with or without sugar-derived structures in the polymer side chains were synthesized and their application to materials for cell cultivation was investigated. Polysilacyclobutanes having glucose-derived moieties or N-acetylglucosamine-derived moieties (polyBMSB-glucose and polyBMSB-AGA) were synthesized by ene-thiol reaction between precursor poly(1-(3-butenyl)-1-methylsilacyclubane)(polyBMSB) and tetraacetylglucose or tetraacetylglucosamine having a thiol group at the anomeric position and the successive deprotection of the acetyl groups gave polycarbosilanes with sugar-derived structures in the side chains. Poly(1-(3-hydroxybutyl)-1-methylsilacyclobutane) was synthesized by hydroboration/oxidation of the precursor polyBMSB. The cell cultivation efficiency using the polymers with or without sugar moieties was evaluated by cultivation of WRL cells on the polystyrene dishes coated with the polymers.

    Reactive isocyanate groups were protected and stabilized by the hydrophobic styrene segment and acquired high tolerance toward water. Copolymers containing isocyanate groups were synthesized by a radical copolymerization of 2-propenyl isocyanate (2PI) and styrene (St). The stability of the obtained copolymers on water was examined to find that isocyanate groups were protected by the hydrophobic polystyrene segment and were stable on water and these isocyanates reacted with primary amines including amino acids to form urea selectively on water. Primary amines with a higher octanol-water partition coefficient or smaller steric hindrance were more reactive to the isocyanate groups in the side chain of the copolymer. The protection of reactive isocyanate groups using the hydrophobic styrene segment did not give side products which are produced in the usual chemical protection/deprotection process.

    -Methylglycidyl ethers have been applied to Electrical and Electronic adhesives. However, there is no report about the detailed polymerization behavior and physical properties of their cured products. Hence, we investigated cationic polymerization behavior of bisphenol A di(-methylglycidyl) ether (Me-BADGE) and physical properties of the cured products containing Me-BADGE. DSC analysis suggested that Me-BADGE could be cured completely at lower temperature than bisphenol A diglycidyl ether (BADGE). Physical properties were analyzed by dynamic viscoelastic analysis. Glass transition temperature (T-g) of BADGE homopolymer was 194 degrees C. In contrast, the copolymer of BADGE (50 wt %) with Me-BADGE (50 wt %) showed T-g at 124 degrees C. According to the data of E' and tan , crosslink density of the cured products decreased with increasing the Me-BADGE content. The analysis of cationic polymerization of monofunctional -methylglycidyl ether suggested that the cationic polymerization proceeded not only through oxonium cation but also through carbocation formed by ring-opening reaction of oxonium cation.

    Polyaddition of bis(five-membered cyclic dithiocarbonate), 2,2-bis[4-(1,3-thioxolane-2-one-4-yl-methoxy)phenyl]propane (1), with diamines having soft oligoether segments and property of the obtained poly(thiourethane)s were examined. Treatment of 1 with equivalent diamines in tetrahydrofuran at room temperature gave poly(thiourethane)s having a mercapto group in each unit, which were further treated with acetic anhydride and triethylamine to give the corresponding S-acetylated poly(thiourethane)s in high yield. Exposing the mercapto group containing poly(thiourethane)s to benzoyl chloride and triethylamine provided the corresponding S-benzoylated poly(thiourethane)s effectively. Thermal properties of the obtained polymers were evaluated by thermogravimetric analysis and differential scanning calorimetry. The obtained polymers showed 10 wt % loss temperature (T-d10) in the range from 230 to 274 degrees C, which was relatively high when compared with the T-d10 of an analogous polymer prepared from 1 and 1,6-hexamethylenediamine. The polymers obtained here exhibited glass transition temperature (T-g) in the range from -16 degrees C to 40 degrees C, which was much lower than the analogous polymer described above, probably due to the soft oligoether segments.

    Polycarbosilanes, which have a carbon-silicone backbone, are highly flexible polymers with excellent thermal, chemical, and electrical stability. They can be readily prepared by ring-opening polymerization of silacyclobutane derivatives. Although polysilacycobutanes are non-polar in general, they can be compatible to carbonate-based electrolyte solutions by introducing a 5-membered cyclic carbonate structure as a pendant group, and if properly designed they can be promising candidates as gelators to prepare gel polymer electrolytes (GPE). We designed a new carbosilane-based GPE system, which could be prepared by ring-opening polymerization of a silacyclobutane having a 5-membered cyclic carbonate structure, 4-{2-(1-methylsilacyclobutyl)}ethyl-1,3-dioxolane-2-one (SBMC). The GPEs were directly synthesized by copolymerization of the monomer with a crosslinker, 1,6-bis(1-methylsilacyclobutyl)hexane (HMBS), in situ of a battery electrolyte solution consisting of 1M LiPF6 in an ethylene carbonate (EC) / diethyl carbonate (DEC) mixed solvent. The obtained GPE showed relatively high ionic conductivity compared to usual liquid electrolytes, and the lithium ion batteries composed of this GPE showed charge/discharge performance as high as those composed of the usual liquid electrolyte.

    Polymerization of a silacyclobutane having an epoxy moiety and its application to networked polymer synthesis were examined. Four-membered ring-opening polymerization of silacyclobutane having a 3,4-epoxybutyl group on the silicon atom (OBMSB) was achieved by using a platinum vinyldisiloxane complex with keeping the epoxy ring unchanged. Copolymerization of 1,1-diethylsilacyclobutane (DESB) with OBMSB by using the same catalyst effectively gave the corresponding copolymers [poly(DESB-co-OBMSB)]. Thermal properties of the polyOBMSB, polyDESB, and poly(DESB-co-OBMSB) were investigated by DSC and TGA. Cast films of the obtained polymers with 1-naphthylmethylmethyl-p-hydroxyphenylsulfonium hexafluoroantimonate, a small amount of thermally latent acid generator were prepared. Heating the films at 80 degrees C for 2 h gave crosslinked networked polycarbosilanes through cationic ring-opening of the epoxy moieties. Thermal and mechanical properties of the networked polymers were investigated by TGA, DSC, and tensile strength measurements. (c) 2014 Wiley Periodicals, Inc. J. Polym. Sci., Part A: Polym.

    An ionic liquid, 1-ethyl-3-(3-ethyl-3-oxetanylmethyl) imidazolium bis(trifluoromethanesulfonyl) imide (OXIm-TFSI), was synthesized, and its cationic polymerization was examined. The heating of a mixture of 1-ethylimidazole and 3-chloromethyl-3-ethyloxetane at 90 degrees C for 48 h yielded 1-ethyl-3-(3-ethyl-3-oxetanylmethyl) imidazolium chloride, which was transformed to a room-temperature ionic liquid, OXImTFSI, by ion exchange with lithium bis(trifluoromethanesulfonyl) imide (LiTFSI). This ionic liquid was polymerized using boron trifluoride ethyl ether complex as a catalyst to give polyOXImTFSI. Five percent weight loss temperature (T-d5) of polyOXImTFSI evaluated by thermal gravimetric analysis was 409 degrees C, indicating the high thermal stability. Glass transition temperature (T-g) of the polymer evaluated by differential scanning calorimetry was -19 degrees C, indicating the high flexibility of the material. Ionic conductivity of polyOXImTFSI was determined to be 1.86 x 10(-8) S/cm at 23 degrees C, which was far lower than that of the OXImTFSI monomer (5.05 x 10(-4) S/cm).

    Reactivity of isothiocynate moieties in the side chain of polymethacrylate with amine, alcohol, or thiol was investigated, and the reactions were applied to preparation of networked polymers. Isothiocyanate of polymer side chain rapidly reacted with amines without a catalyst, to give the corresponding thioureas. However, it did not react with alcohols or thiols under the same conditions. Using 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU) as a catalyst, addition of alcohols or thiols to the isothiocyanate proceeded smoothly. Addition of amines, alcohols, and thiols to isothiocyanates moiety contained in the side chain of polymethacrylate also proceeded readily with or without the catalyst, respectively, to effectively give the corresponding side chain modified polymers. Occurrence of these additions was confirmed by 1H NMR and IR measurements. Glass transition temperatures and thermal decomposition temperatures of the obtained polymers were investigated by differential scanning calorimetry and thermogravimetric analysis. Networked polymers were easily prepared by addition of 1,6-hexamethylenediamine or hexamethylene glycol to the polymethacrylate having isothiocyanato groups. (c) 2014 Wiley Periodicals, Inc. J.

    Novel styrene monomers bearing a five or seven-membered spiroorthoester structure (SOE5, SOE7) were synthesized and their radical polymerizations as well as volume change during crosslinking of the obtained polymers were investigated. SOE5 and SOE7 were prepared from 4-vinylbenzyl glycidyl ether and -butyrolactone or epsilon-caprolactone using boron trifluoride diethyl ether complex as a catalyst, respectively. Radical polymerizations of these monomers using 2,2-azobisisobutyronitrile (AIBN) gave the corresponding styrene-based polymers with keeping the spiroorthoester structures unchanged. These polymers could be transformed to networked polymers by heating with a sulfonium antimonate, a thermally latent cationic polymerization initiator. Copolymerization of SOE5 or SOE7 with styrene at various compositions was carried out to efficiently obtain the corresponding copolymers, respectively. These polymers and copolymers showed little volume shrinkage or slight volume expansion during the crosslinking. (c) 2014 Wiley Periodicals, Inc. J. Polym. Sci., Part A: Polym.

    Radical copolymerizations of 2-isothiocyanatoethyl methacrylate (ITEMA) and 2-hydroxyethyl methacrylate (HEMA) or methacrylic acid (MAA) were examined, and fundamental properties of the obtained copolymers were investigated. The copolymerizations of various ITEMA/HEMA or ITEMA/MAA compositions proceeded effectively in THF or DMF by using 2,2-azobisbutyronitrile (AIBN) as an initiator, keeping the isothiocyanato groups and hydroxyl or carboxyl groups unchanged. Glass transition temperatures (T-g)s of poly(ITEMA-co-HEMA)s ranged from 68 to 100 degrees C, and they were thermally stable up to 200 degrees C. Meanwhile, T(g)s of poly(ITEMA-co-MAA)s (ITEMA/MAA = 91/9, 76/24) were determined to be 91 and 109 degrees C, respectively. However, poly(ITEMA-co-MAA)s were thermally unstable, and significant weight loss was observed around 180 degrees C, which may be due to an addition of carboxyl groups to isothiocyanato groups followed by an elimination of COS to form amide structure in the copolymers.

    Polymers having a sugar moiety in the side group have been utilized as artificial matrices for cell adhesion in tissue engineering. In this study, methacrylamide - based polymers having lactose and maltose derivative structures in the side group with various aliphatic hydrocarbon spacers were synthesized, and their cell adhesion properties were examined. Methacrylamide monomers were prepared by two step amidation of a spacer diamine, first with a sugar lactone and then with a methacrylic anhydride. These monomers were radically polymerized in aqueous media using 4,4-azobis(4-cyanovaleric acid) (ACVA) as radical initiator to give the corresponding polymethacrylamide. Specific interaction between these polymers and animal cell was investigated by adhesion of proliferated human liver cancer cell (WRL) to the polymethacrylamides. WRL interacted with polymers having a lactose structure with a hexamethylene or 1,4-cyclohexylene spacer by a specific manner and was promoted typical spheroid formation, while it did not interacted with polymers having a maltose structure.

    Anionic ring-opening polymerizations of methyl 4,6-O-benzylidene-2,3-O-carbonyl--D-glucopyranoside (MBCG) were investigated using various anionic polymerization initiators. Polymerizations of the cyclic carbonate readily proceeded by using highly active initiators such as n-butyllithium, lithium tert-butoxide, sodium tert-butoxide, potassium tert-butoxide, and 1,8-diazabicyclo[5.4.0]undec-7-ene, whereas it did not proceed by using N,N-dimethyl-4-aminopyridine and pyridine as initiators. In a polymerization of MBCG (1.0 M), 99% of MBCG was converted within 30 s to give the corresponding polymer with number-averaged molecular weight (Mn) of 16,000. However, the Mn of the polymer decreased to 7500 when the polymerization time was prolonged to 24 h. It is because a backbiting reaction might occur under the polymerization conditions.

    A styrene-based monomer having a five-membered cyclic dithiocarbonate structure, 4-vinylbenzyl 1,3-oxathiolane-2-thione-5-ylmethyl ether (VBTE), was synthesized from 4-vinylbenzyl glycidyl ether (VBGE) and carbon disulfide in the presence of lithium bromide in 86% yield. Radical polymerization of VBTE in dimethyl sulfoxide by 2,2-azobisisobutyronitrile was carried out at 60 degrees C to afford the corresponding the polymer, polyVBTE, in 64% yield. PolyVBTE with number-averaged molecular weight higher than 31,000 was obtained. The glass transition temperature (Tg) and 5 wt % decomposition temperature (Td5) of the polyVBTE were evaluated to be 66 and 264 degrees C under nitrogen atmosphere by differential scanning calorimetry and thermal gravimetry analysis, respectively. It was confirmed that a polymer consisting of the same VBTE repeating unit could also be obtained via polymer reaction, that is, a lithium bromide-catalyzed addition of carbon disulfide to a polyVBGE prepared from a radical polymerization of VBGE. Copolymerization of VBTE and styrene with various compositions efficiently gave copolymers of VBTE and styrene. (c) 2012 Wiley Periodicals, Inc. J Polym Sci Part A: Polym Chem, 2013

    To develop ionic-conductive film-shaped electrolytes with high reliability, we designed and synthesized the following networked polymers with an epoxy/amine curing system using poly(ethylene glycol) as the main skeleton, and examined their fundamental properties such as ionic conductivity, thermal stability, and inflammability. (1) Networked polymers having quaternary ammonium salt structures. (2) Networked polymers having lithium sulfonate salt structures. (3) Networked polymers having lithium sulfonylimide salt structures. (4) Networked polymers swollen with ionic liquid solutions of lithium salts. Consequently, we found that networked polymers swollen with ionic liquid solutions containing lithium salts showed high ionic conductivity and high thermal stability with excellent non-flammability.

    A silacyclobutane having a five-membered cyclic carbonate structure (SBMC) was prepared, and its transition metal-catalyzed ring-opening polymerization at the four-membered carbosilane unit was investigated as well as formation of carbosilane networked polymers and polymer gel electrolytes. The SBMC was synthesized by epoxidation of 1-(4-butenyl)-1-methylsilacyclobutane followed by insertion of CO2 to the epoxide. Ring-opening polymerization of the silacyclobutane moiety in the SBMC readily proceeded by a transition metal catalyst such as platinum divinyltetramethyldisiloxane complex. A flexible networked polymer film was obtained by copolymerization of the SBMC with a small amount of crosslinker, hexamethylene-1,6-bis(1-methylsilacyclobutane) (HMBS).

    A styrene-based monomer having a five-membered cyclic carbonate structure, 4-vinylbenzyl 2,5-dioxoran-3-ylmethyl ether (VBCE), was prepared by lithium bromide-catalyzed addition of carbon dioxide to 4-vinylbenxyl glycidyl ether (VBGE). Radical polymerization of the obtained VBCE was carried out using 2,2'-azobisisobutyronitrile as an initiator. PolyVBCE with number-averaged molecular weight higher than 13,800 was obtained by a solution polymerization in N,N-dimethylformamide, N,N-dimethylacetamide, dimethyl sulfoxide, and methyl ethyl ketone. The glass transition temperature and 5 wt % decomposition temperature of the polyVBCE were determined to be 52 and 305 degrees C by differential scanning calorimetry and thermal gravimetry analysis, respectively. It was confirmed that a polymer consisting of the same VBCE repeating unit can be also obtained via chemical modification of polyVBGE, that is, a lithium-bromide-catalyzed addition of carbon dioxide to a polyVBGE prepared from a radical polymerization of VBGE. Further copolymerization of VBCE with styrene gave the corresponding copolymer in a high yield. (c) 2012 Wiley Periodicals, Inc. J Polym Sci Part A: Polym Chem, 2012

    Self-standing films of (meth)acrylate-based polymer gel electrolytes with high ionic liquid content (80 wt %) were prepared by in situ thermally or photo induced radical copolymerization of mono-functional and di-functional (meth)acrylates in an ionic liquid in the presence/absence of a lithium salt. Their ionic conductivity, thermal property, mechanical property, and flammability were examined. 1-Ethyl-3-methylimidazolium bis(trifluoromethanesulfonyl)imide (EMImTFSI) or 1-ethyl-3-methylimidazolium bis(fluorosulfonyl)imide (EMImFSI) was used as the ionic liquid, and lithium bis(trifluoromethanesulfonyl)imide LiTFSI was used as the lithium salt. The obtained films were semitransparent and flexible with good to moderate thermal stability and mechanical strength with high ionic conductivity. The EMImFSI-containing gel electrolytes showed higher ionic conductivity than the corresponding EMImTFSI-containing gel electrolytes. The ionic conductivity in the acrylate-based gel electrolytes was slightly increased by addition of lithium salt, while that in the corresponding methacrylate-based electrolytes was decreased significantly. The flame test showed the ionic liquid containing networked polymer gel electrolytes to have low if any flammability and was therefore confirmed to be highly safe. (c) 2012 Wiley Periodicals, Inc.

    The ionic amphiphilic diblock copolymers, (n-butyl acrylate)(m)-b-(styrene sulfonate)(n), were synthesized by nitroxy radical mediated living radical polymerization with precise control of degree of polymerization and molecular weight distribution. Several polymers with different m and n values at m : n = 1 : 1 were obtained, and their non-surface activity was examined by surface tension experiments and foam formation observation. All the polymers with m = n = 7-50 were found to form micelles in aqueous solutions, but the polymers with a degree of polymerization larger than 20 showed non-surface activity while those less than 20 were found to be surface active. As with other polymers investigated previously, surface activity was observed when salts were added to the solution, even for polymers of a non-surface active nature in pure water solution. This means that non-surface activity is not only an electrostatic effect (image charge effect at the air/water interface) but also some kind of polymer effect. Non-surface activity is a specific characteristic only for polymers, and the border of "amphiphilic polymer" and "low molecular weight surfactant" is located around the degree of polymerization of about 20. This is proposed as a new definition of "polymer" from the view of surface science, at least, from the view of non-surface activity. The essential of this "polymer effect" can be attributed to the highly stable nature of polymer micelles in solution compared to adsorbed polymer at the air/water interface, which is highly destabilized by image charge repulsion.

    Ionic-liquid-containing polymer films were prepared by swelling poly(ethylene glycol)-based networked polymers having lithium salt structures with an ionic liquid, 1-ethyl-3-methylimidazolium bis(fluorosulfonyl) imide (EMImFSI), or with an EMImFSI solution of lithium bis(trifluoromethanesulfonyl) imide (LiTFSI). Their fundamental physical properties were investigated. The networked polymer films having lithium salt structures were prepared by curing a mixture of poly(ethylene glycol) diglycidyl ether and lithium 3-glycidyloxypropanesulfonate or lithium 3-(glycidyloxypropanesulfonyl)(trifluoromethanesulfonyl) imide with poly(ethylene glycol) bis(3-aminopropyl) terminated. The obtained ionic-liquid-containing films were flexible and self-standing. They showed high ionic conductivity at room temperature, 1.16-2.09 S/m for samples without LiTFSI and 0.29-0.43 S/m for those with 10 wt % LiTFSI. Their thermal decomposition temperature was above 220 degrees C, and melting temperature of the ionic liquid incorporated in the film was around -16 degrees C. They exhibited high safety due to good nonflammability of the ionic liquid. (C) 2011 Wiley Periodicals, Inc. J Polym Sci Part A: Polym Chem 49: 3582-3587, 2011

    Networked polymers that had poly(ethylene glycol) (PEG) chains and lithium sulfonylimide salt structures were prepared by curing a mixture of poly(ethylene glycol) diglycidyl ether and lithium 3-glycidyloxypropanesulfonyl-trifluoromethanesulfonylimide with poly(ethylene glycol) bis(3-aminopropyl) terminated. The obtained flexible self-standing networked polymer films showed high thermal and mechanical stability with relatively high ionic conductivity. The room temperature ionic conductivity under a dry condition was in the range of 10(-5) similar to 10(-4) S m(-1), which is one order of magnitude higher than the corresponding networked polymers having lithium sulfonate salt structures (10(-6) similar to 10(-5) S m(-1)). The film sample became swollen by immersing in propylene carbonate (PC) or PC solution of lithium bis(trifluoromethanesulfonyl) imide (LiTFSI). The sample swollen in PC showed higher ionic conductivity (7.2 x 10(-3) S m(-1) at room temperature), and the sample swollen in 1.0 M LiTFSI/PC showed much higher ionic conductivity (8.2 x 10(-1) S m(-1) at room temperature).

    Ionic networked polymers containing ionic liquids were synthesized by radical copolymerization of 1-(2-methacryloyl)ethyl-3-methylimidazolium bis(trifluoromethanesulfonyl)imide (Met-IL) and difunctional or trifunctional methacrylate cross-linkers, ethylene glycol dimethacrylate (EGDMA), or trimethylolpropane trimethacrylate (TMPTMA) in the presence of an ionic liquid, 1-ethyl-3-methylimidazolium bis(trifluoromethanesulfonyl)imide (EMImTFSI). For comparison, nonionic networked polymers containing the ionic liquid were prepared by radical copolymerization of methyl methacrylate (MMA) with EGDMA in the presence of EMImTFSI. Met-IL/EGDMA/EMImTFSI(50) showed higher ion conductivity and ionic liquid holding ability than the corresponding MMA/EGDMA/EMImTFSI(50), while Met-IL/TMPTMA/EMImTFSI(50) showed lower ionic conductivity with higher holding ability than MMA/EGDMA/EMImTFSI(50).

    Azobisisobutyronitlite (AIBN)-induced free radical polymerization of a methacrylate-based ionic liquid monomer, 1-(2-methacryloxyethyl)-3-methylimidazolium bis(trifluoromethanesulfonyl)imide (Met-IL) was carried out in a common organic solvent, N,N-dimethylformamide (DMF), and an ionic liquid, 1-ethyl-3-methylimidazolium bis(trifluoromethanesulfonyl)imide (EMImTFSI). The molecular weight of the obtained poly(Met-IL) was evaluated by transforming it to non-ionic poly(methyl methacrylate) with hydrolysis of the imidazolium-salt-substituted pendant ester groups and methyl esterification. Radical copolymerization with methyl methacrylate (MMA) was also carried out in both DMF and EMImTFSI. Analysis of copolymer composition revealed that the reactivity of Met-IL was lower than that of MMA in both DMF and EMImTFSI solutions.

    Methacrylate-based networked polymers having ionic liquid structures were prepared by radical copolymerization of methyl methacrylate (MMA) with multifunctional crosslinkers: ethyleneglycol dimethacrylate (EGDMA), trimethylolpropane trimethacrylate (TMPTMA), or triethyleneglycol dimethacrylate (TEGDMA), in the presence of 1-ethyl-3-methylethyl-1-imidazolium bis(trifluoromethane) sulfonyl imide (EMImTFSI). The fundamental physical properties of several film samples prepared by varying the monomer composition and ionic liquid content were investigated. The obtained materials became turbid with increasing crosslinker content and ionic liquid content. Their ionic conductivity increased with increasing ionic liquid content, while it was almost independent of the crosslinker content. EGDMA-derived materials and TMPTMA-derived materials showed higher ionic conductivity than TEGDMA-derived materials. TMPTMA-derived materials showed higher thermal stability than EGDMA or TEGDMA-derived materials. EGDMA and TMPTMA-derived materials were stiffer than the TEGDMA-derived materials. The elastic modulus of the film samples increased but the film became more brittle with the increase of crosslinker content. Scanning electron microscopy and atomic force microscopy observation revealed that phase separation of networked polymers and ionic liquid occurred in the highly crosslinked samples, and the phase separation structures became larger in scale with the increase of crosslinking density. This phase separation was considered to have a strong effect on the mechanical properties of the film samples. (C) 2010 Wiley Periodicals, Inc. J Polym Sci Part A: Polym Chem 48: 4515-4521, 2010

    Poly(ethylene glycol)-based networked polymers that had lithium sulfonate salt structures on the network were prepared by heating a mixture of poly(ethylene glycol) diglycidyl ether (PEGGE), poly(ethylene glycol) bis(3-aminopropyl) terminated (PEGBA), and an ionic epoxy monomer, lithium 3-glycidyloxypropanesulfonate (LiGPS). Flexible self-standing networked polymer films showed high thermal stability, low crystallinity, low glass transition temperature, and good mechanical strength. The materials were ion conductive at room temperature even under a dry condition, although the ionic conductivity was rather low (10(-6) to 10 (5) S/m). The ionic conductivity increased with the increase in temperature to above 1 x 10 (4) S/m at 90 degrees C. The film samples became swollen by immersing in propylene carbonate (PC) or PC solution of lithium bis(trifluoromethanesulfonyl)imide (LiTFSI). The samples swollen in PC showed higher ionic conductivity (ca.1 x 10(-3) S/m at room temperature), and the samples swollen in LiTFSI/PC showed much higher ionic conductivity (nearly 1 S/m at room temperature).

    The design strategy and synthesis of bulky, hydrophobic, and thermally, stable adamantyl methacrylate monomers with attached hydrophilic and acid labile three different types of alkyl (1 degrees, 2 degrees, 3 degrees) hemiacetal side groups are described. Free radical polymerizations of the obtained monomers furnished the desired polymers with high molecular weights. The properties such its thermal stability, moisture stability, and acid sensitivity of the obtained adamantyl hemiacetal ester homopolymers were evaluated which showed strong structure-property dependence. The bond dissociation enthalpy of the obtained polymers depended oil the electronic effects of the type of pendant hemiacetal ester side groups.

    The nanostructure and its transition of in a poly(acrylic acid) (PAA) brush ill the water surface monolayers of poly(hydrogenated isoprene)-b-poly(acrylic acid) with different block lengths and block ratios were investigated by X-ray reflectivity as a function of surface pressure (brush density) and salt concentration in the subphase. The PAA brush showed the same behavior after salt addition as did the poly(methacrylic acid) (PMAA) brush, which was investigated previously. The brush chains expanded and then shrunk after passing the maximum with increasing added salt concentration. This behavior could be explained by the change in electric charges on the PAA brush chains as was observed on the PMAA brush. The PAA brush chains showed a critical brush density, where there was a transition between the carpet layer only and carpet + brush layer structures, as did the PMAA and poly(styrene sulfonic acid) (PSS) brushes. The critical brush density was about 0.4 chains nm(-2), which was higher than that of the PSS brush, a strong acid brush, and was close to that of the PMAA brush, a weak acid brush. However, the critical brush density of the PAA brush was independent of the hydrophilic chain length whereas that of the PMAA brush decreased with increasing PMAA chain length. In addition, the PAA brush had a thicker carpet layer than the PSS and PMAA brushes. Hence, the mechanism of PAA brush formation was predicted to be different from that of not only the PSS brush (strong acid brush) but also the PMAA brush.

    Amphiphilic diblock copolymers such as poly(styrene)-block-poly(styrene sulfonate) (PS-b-PSS) (Matsuoka, H.; Maeda, S.; Kaewsaiha, P.; Matsumoto, K. Langmuir 2004, 20, 7412), belong to a class of new polymeric surfactants that ionize strongly in aqueous media. We investigated their self-assembly behavior in aqueous solutions and used them as an emulsifier to prepare electrosterically stabilized colloidal particles of different diameters between 70 to 400 nm. We determined the size, size polydispersity, effective charge, total dissociable charge, structural ordering, and phase behavior using light scattering, transmission electron microscopy (TEM), small-angle neutron scattering (SANS), and potentiometric titration. These experiments clearly demonstrated that all of the synthesized particles were nearly monodisperse (polydispersity index <= 6%). The results of DLS and TEM clearly suggested the existence of hairy particles. The form factors obtained by SANS were well described by a polydisperse sphere model. The estimated total number of dissociable charges per particle was found to be larger than 10(4)e, whereas the effective charges per particle were found to be around 1000e. This significant difference suggested the confinement of charges inside the corona regions of the polyelectrolyte brush shell. Finally, these monodisperse particles were found to self-assemble into 3D ordered colloidal crystalline arrays at a low volume fraction (= 0.00074) that diffract light in the visible region.

    Networked polymers confining an ionic liquid, 1-ethyl-3-methylimidazolium bis(trifluoromethanesulfonyl) imide (EMImTFSI), were prepared by curing a mixture of bisphenol A diglycidyl ether (BADGE) and tetrafunctional epoxy resins with tetraethylenepentamine (TEPA) in the presence of ionic liquid. It was found that addition of the tetrafunctional epoxy resins was inevitable for better ionic liquid confinement. The ionic liquid confinement, ionic conductivity, mechanical strength, and morphology of the materials strongly depended on the ionic liquid content. At a low ionic liquid content (< 40 wt %), the material tightly confined the ionic liquid and showed little ionic conductivity with a high Young's modulus, while at a high ionic liquid content (> 40 wt %), it did not confine the ionic liquid showing higher ionic conductivity with a low Young's modulus. At a high ionic liquid content (> 40 wt %), microphase separation between the ionic liquid and the epoxy networked polymer was observed by scanning electron microscopy (SEM). A transition of the microphase separation from discrete sphere to continuous structure was also observed between 40 wt % and 50 wt % ionic liquid contents. This morphology transition caused a drastic change of the material properties around these ionic liquid contents. © 2008 American Chemical Society.

    Diblock copolymer membranes having a fluorinated segment and a sulfonic acid segment were prepared by living radical polymerization, solution casting, and crosslinking, followed by heat treatment. Diblock copolymers of 2,3,4,5,6-penta-fluorostyrene (PFS)/4-(1-methylsilacyclobutyl)styrene (SBS) and neopentyl styrenesulfonate (SSPen) (poly(PFS-co-SBS)-b-polySSPen)s were synthesized by nitoroxy-mediated living radical polymerization. Self-standing crosslinked membranes were obtained by casting a THF solution of the block copolymer with Pt catalyst. Heat treatment of the membrane at 230 degrees C induced decomposition of the neopentyl sulfonate esters to provide block copolymer membranes having a fluorinated segment and a free sulfonic acid segment. It was confirmed that the block copolymer with a high sulfonic acid content exhibited high ion exchange capacity and high proton conductivity as well as high thermal stability.

    Micellization behavior of amphiphilic diblock copolymers with strong acid groups, poly(hydrogenated isoprene)-block-poly(styrenesulfonate), was investigated by small-angle neutron scattering (SANS). We have reported previously (Kaewsaiha, P.; Matsumoto, K.; Matsuoka, H. Langmuir 2005, 21, 9938) that this strongly ionic amphiphilic diblock copolymer shows almost no surface activity but forms micelles in water. In this study, the size, shape, and internal structures of the micelles formed by these unique copolymers in aqueous solution were duly investigated. The SANS data were well described by the theoretical form factor of a core-shell model and the Pedersen core-corona model. The micellar shape strongly depends on the hydrophobic chain length of the block copolymer. The polymer with the shortest hydrophobic chain was suggested to form spherical micelles, whereas the scattering curves of the longer hydrophobic chain polymers showed a q(-1) dependence, reflecting the formation of rodlike micelles. Furthermore, the addition of salt at high concentration also induced the sphere-to-rod transition in micellar shape as a result of the shielding effect of electrostatic repulsion. The corona thickness was almost constant up to the critical salt concentration (around 0.2 M) and then decreased with further increases in salt concentration, which is in qualitatively agreement with existing theories. The spherical/rodlike micelle ratio was also constant up to the critical salt concentration and then decreased. The micelle size and shape of this unique polymer could be described by the common concept of the packing parameter, but the anomalously stable nature of the micelle (up to 1 M NaCl) is a special characteristic.

    The nanostructure of a spread monolayer of diblock copolymers of poly(hydrogenated isoprene) and poly(styrenesulfonate) at the air/water interface were studied by in situ X-ray reflectivity as a function of the brush density and salt concentration. When the monolayer was compressed beyond the "critical brush density", its nanostructure changed from a flat, adsorbed "carpet" layer to a "carpet + brush" structure. The critical brush density was found to be about 0.12 nm(-2), independent the brush length and salt concentration under a low-salt condition. The brush formation behavior was considered to be controlled by an electrostatic interaction between polyelectrolyte chains rather than by a steric hindrance. This might be because the distance between the chains at the critical point is rather long and also because of the effect of the salt on the critical brush density. The critical brush density increased at higher added salt concentration beyond 1 M. As a result, we found a new structure transition behavior of the polymer brushes between carpet-only and carpet + brush structures, which was induced by salt addition. Finally, we succeeded in the controlled release of salt ions from the salted brush layer by changing the brush density by compression of the monolayer.

    Fluorinated polymer particles with grafting sulfonate chains, which showed high dispersion stability in aqueous media, were synthesized by the crosslinking of block copolymer micelles. A crosslinkable block copolymer, poly[(2,3,4,5,6-pentafluorostyrene)-co-4-(1-methylsilacyclobutyl)styrenel-b-poly(neopentyl 4-styrenesulfonate), composed of a statistical copolymer segment of 2,3,4,5,6-pentafluorostyrene with 4-(1-methylsilacyclobutyl)styrene and a neopentyl 4-styrenesulfonate segment, was prepared by the nitroxy-mediated living radical polymerization of a 2,3,4,5,6-pentafluorostyrene/4-(1-methylsilacyclobutyl)styrene mixture and neopentyl 4-styrenesulfonate. The block copolymer formed micelles with a poly[(2,3,4,5,6-pentafluorostyrene)-co-4-(1-methylsilacyclobutyl)styrene] core in acetonitrile, which were crosslinked via the ring-opening reaction of silacyclobutyl groups in the core by a treatment with a platinum catalyst. The deprotection of sulfonate groups in the micelle corona by exposure to trimethylsilyl iodide and a treatment with aqueous HCl, followed by neutralization with aqueous NaOH, provided a polymer particle with polymer chains of sodium 4-styrenesulfonate grafted on its surface.

    The strong polyelectrolyte layer in the monolayer of ionic amphiphilic diblock copolymers at the air/water interface consists of carpet and brush layers when the brush density is satisfactorily high like that of the weak acid polymer. Also, a drastic structural change was induced by the addition of salt to the brush layer. In this study, the critical brush density for the transition between "carpet-only" and "carpet + brush" structures for the strongly ionic amphiphilic diblock copolymer, poly(hydrogenated isoprepene)-b-poly(styrene sulfonic acid) sodium salt, monolayer was measured by an in situ X-ray reflectivity technique. The critical brush density was found to be about 0.12 nm(-2), which is lower than that observed for a weak acid polymer and, unlike the weak acid polymer, is independent of the hydrophilic chain length. This difference might be attributed to the strong ionic nature of the brush chain. In addition, the reversibility of the transition was confirmed. The effect of salt addition to the nanostructure of the carpet layer was examined in detail. No structural change was found, indicating that most of the ionic groups in the carpet layer do not show an ionic nature because of counterion condensation.

    The detailed structure and unique characteristics of a sodium poly(4-styrenesulfonate)-grafted nanoparticle, CCL-SBS113-b-SSNa208, were investigated, where CCL, SBS, and SSNa represent a core-cross-linked micelle, 4-(1-methylsilacyclobutyl)styrene, and sodium 4-styrenesulforiate, respectively. The particle nanostructure was analyzed by small-angle neutron scattering (SANS), dynamic light scattering (DLS), and atomic force microscopy. SANS data suggested that the particle had a core-corona structure with a 14-nm core radius (R-c) and 2-nm radius of gyration (R-g) corona-forming chain in water. DLS analysis revealed that the hydrodynamic radius (R-h) of particle was 100 nm in water, which is much larger than the whole particle size evaluated by SANS, but the Rh value gradually decreased with addition of NaCl and reached a constant value of 61 nm at an NaCl concentration above 0.2 M. Conductometric titration of the acidic form sample with NaOHaq suggested that the CCL-micelle had exactly the same content of sulfonate groups as the precursor block copolymer. The polySSNa-grafting particle showed high solution stability toward salt addition, which may be due to the electrostatic stabilization effect in addition to steric stabilization by the grafting polymer chains.

    Diblock copolymer poly(1,1,3,N,N'-pentamethyl-3-vinylcyclodisilazane)-block-polystyrene (polyVSA-b-polySt) and triblock copolymer poly(1,1,3,N,N'-pentamethyl-3-vinylcyclodisilazane)-block-polystyrene-block-poly(1,1,3,NA7-pentamethyl-3-vinylcyclodisilazane) (polyVSA-b-polySt-b-polyVSA), consisting of silazane and nonsilazane segments, were prepared by the living anionic polymerization of 1,1,3,N,N'-pentamethyl-3-vinylcyclodisilazane and styrene. PolyVSA-b-polySt formed micelles having a poly(1,1,3,N,N'-pentamethyl-3-vinylcyclodisilazane) (polyVSA) core in N,N-dimethylformamide, whereas polyVSA-b-polySt and polyVSA-b-polySt-b-polyVSA formed micelles having a polyVSA shell in n-heptane. The micelles with a polyVSA core were core-crosslinked by UV irradiation in the presence of diethoxyacetophenone as a photosensitizer, and the micelles with a polyVSA shell were shell-crosslinked by UV irradiation in the presence of diethoxyacetophenone and 1,6-hexanedithiol. These crosslinked micelles were pyrolyzed at 600 degrees C in N-2 to give spherical ceramic particles. The pyrolysis process was examined by thermogravimetry and thermogravimetry/mass spectrometry. The morphologies of the particles were analyzed by atomic force microscopy and transmission electron microscopy. The chemical composition of the pyrolysis products was analyzed by X-ray fluorescence spectroscopy and Raman scattering spectroscopy. (c) 2006 Wiley Periodicals, Inc.

    Novel, monodisperse charged colloidal particles of polystyrene cross linked with divinylbenzene and surface-grafted with acrylic acid were synthesized by emulsion polymerization and were characterized by estimating the dissociable surface charge by conductivity titration, the particle effective charge by conductivity verses particle concentration, and the particle size by dynamic light scattering and atomic force microscopy. The structural ordering and dynamics were investigated as a function of the volume fraction of the particles using static and dynamic light scattering, respectively. Furthermore, front the electrophoresis measurements, these particles are found to have a high salt tolerance due to increases in charge as a function of salt concentration.

    Novel polyelectrolyte grafted charged colloidal particles have been synthesized via emulsion polymerization method using block copolymer as an emulsifier and have been characterized by determining the surface charge number (Z), chain density (sigma) using conductometric titration, the size distribution, hydrodynamic (R-h) radius by dynamic light scattering and the core radius (R-c) by atomic force microscopy. The structural ordering and dynamics have been investigated in a very dilute concentration and the effect of salt concentration (C-s) on hydrodynamic radius have also been studied using dynamic light scattering. The conductivity titration curve was found to show two equivalence points and the potentiometric titration curves are found to sensitive only after a critical salt concentrations. The corresponding measured hydrodynamic radius is also found to decrease after a critical salt concentration. At high salt concentration, the hydrodynamic radius shows a close agreement with that of the core radius measured by the atomic force microscope. These experimental results are in agreement with the recent theoretical prediction and experimental observation that most of the counterions are confined inside the brush region which led to stretching of the chains at low salt concentration.

    Hydrogen fluoride is a basic fluorinating reagent, but handling it is difficult. For this reason, some modified fluorinating reagents such as HF-pyridine, Et3N-HF, and poly(hydrogen fluoride) complex have been developed. Those reagents, however, still require aqueous work-up procedures which generate hydrogen fluoride. Recently, ionic liquids have received much attention because of the ease in handling them and the possibility of non-aqueous work-up. An ionic liquid, 3-ethyl-1-methyimidazolium oligo hydrogen fluoride (EM1MF(HF)(2.3)), which is stable in air and moisture, can be used as a hydrogen fluoride equivalent for some fluorination reactions; it does not require an aqueous work-up.

The structural information about the reagent as THF solution was corrected by small angle neutron scattering and by anomalous X-ray scattering. Those scattering experiments implied that the prepared bis(iodozincio)methane exists without forming any oligomer or aggregate. A coordination of tetrahydrothiophene to bis(iodozincio)methane enhances the nucleophilicity of the reagent and stabilizes its monomeric structure in the solution. (c) 2005 Elsevier B.V.

    Fine particles having poly(p-styrenesulfonic acid) (polySS) in the core and a polystyrene (polySt) shell were synthesized by cross-linking and successive chemical transformation of triblock copolymer micelles. A triblock copolymer, polySt-b-poly(St(0.8)-co-SBS0.2)-b-polySSPen, was synthesized by nitroxide-mediated living radical polymerization, where SBS and SSPen denote p-(1-methylsilacyclobutyl)-styrene and neopentyl p-styrensulfonate, respectively. Block copolymer micelles carrying a polySSPen core and polySt shell with cross-linkable silacyclobutyl groups in the shell were prepared by dissolving the triblock copolymer in cyclohexane. Cross-linking of the shell by Pt-catalyzed ring-opening of silacyclobutane followed by thermolysis of the neopentyl esters in polySSPen in tetralin in the presence of p-toluenesulfonic acid gave the cross-linked micellar particles with polySS in the micelle core. The obtained particles showed unique environmentally responsive solubility due to the core-shell structure with a moderately cross-linked shell.

    We reported previously (Macromolecules 2003, 36, 5321; Langmuir, 2004, 20, 7412) that amphiphilic diblock copolymers having polyelectrolytes as a hydrophilic segment show almost no surface activity but form micelles in water. In this study, to further investigate this curious and novel phenomenon in surface and interface science, we synthesized another water-soluble ionic amphiphilic diblock copolymer poly(hydrogenated isoprene)-b-sodium poly(styrenesulfonate) PIp-h(2)-b-PSSNa by living anionic polymerization. Several diblock copolymers with different hydrophobic chain lengths were synthesized and the adsorption behavior at the air/water interface was investigated using surface tension measurement and X-ray reflectivity. A dye-solubilization experiment was carried out to detect the micelle formation. We found that the polymers used in this study also formed micelles above a certain polymer concentration (cmc) without adsorption at the air-water interface under a no-salt condition. Hence, we further confirmed that this phenomenon is universal for amphiphilic ionic block copolymer although it is hard to believe from current surface and interface science. For polymers with long hydrophobic chains (more than three times in length to hydrophilic chain), and at a high salt concentration, a slight adsorption of polymer was observed at the air-water interface. Long hydrophobic chain polymers showed behavior "normal" for low molecular weight ionic surfactants with increasing salt concentration. Hence, the origin of this curious phenomenon might be the macroionic nature of the hydrophilic part. Dynamic light scattering analysis revealed that the hydrodynamic radius of the block copolymer micelle was not largely affected by the addition of salt. The hydrophobic chain length-cmc relationship was found to be unusual; some kind of transition point was found. Furthermore, very interestingly, the cmc of the block copolymer did not decrease with the increase in salt concentration, which is in clear contrast to the fact that cmc of usual ionic small surfactants decreases with increasing salt concentration (Corrin-Harkins law). These behaviors are thought to be the special, but universal, characteristics of ionic amphiphilic diblock copolymers, and the key factor is thought to be a balance between the repulsive force from the water surface by the image charge effect and the hydrophobic adsorption.

    Carbosilane fine particles were synthesized by core-crosslinking of carbo-silane block copolymer micelles and they were pyrolytically transformed into silica nanoparticles. The carbosilane block copolymer, poly(1-(3-butenyl)-1-methylsilacyclo-butane)-block-polystyrene, (polyBMSB-b-polySt), [(m, n) = (31, 16), (54, 30), and (75, 28)], was synthesized by anionic polymerization of BMSB and St, where m and n represent polymerization degrees of BMSB and St segments, respectively. The block copolymer formed micelles in N,N-dimethylformamide (DMF). The hydrodynamic diameters (D-h) of the micelles evaluated by dynamic light scattering ranged from 40 to 158 nm depending on the copolymer molecular weight. The core of the micelle was cross-linked by Pt-catalyzed hydrosilation with 1,2-bis(dimethylsilylethane). The Dh of the core-cross-linked micelles in THF ranged from 56 to 164 nm. These precursor particles were pyrolyzed at 850 degrees C under N-2 to give ceramic nanoparticles. The diameters of the spherical ceramic particles estimated by AFM ranged from 25 to 60 nm. X-ray fluorescence analysis of the ceramic products revealed that it consisted of mainly SiO2 rather than SiC. (c) 2005 Wiley Periodicals, Inc.

    The critical brush density, where transition from carpet-only structure to carpet/brush double-layered structure occurs, was estimated for a weakly ionic amphiphilic diblock copolymer, (diethylsilacyclobutane)(34)-b-(methacrylic acid)(50), monolayer on water by an in situ X-ray reflectivity technique. The brush density in the monolayer was controlled from 0.11 to 0.60 brush chain/nm(2) by changing surface pressure and mixing a poly(diethylsilacyclobutane) homopolymer separately synthesized. Only a carpet layer was formed at a low brush density condition, but a carpet and brush double layer was found for a higher brush density of more than 0.48/nm(2). This brush density, which is fairly high, would be valuable for discussing the polyelectrolyte brush nanostructure.

    The "carpet/brush double layer structure in the polyelectrolyte layer in the amphiphilic diblock copolymer monolayer at the air-water interface was quantitatively studied by in situ neutron reflectometry in addition to X-ray reflectivity measurements. As a result of the higher contrast between polyelectrolyte [poly(methacrylic acid)] and solvent (D2O) for the neutron, the brush structure could be estimated more accurately as a function of surface pressure, that is, brush density. The thickness of the carpet layer, which is thought to be formed to reduce the interfacial free energy between water and the hydrophobic layer, was almost constant at 10-20 Angstrom at any surface pressure studied. Growth was clearly observed in the whole brush length with increasing surface pressure, and it was estimated to be almost 60% of the full-stretch length of the ionic polymer chain. Furthermore, by the comparison of density profiles by neutron and X-ray reflectometry, an anomalous hydration was suggested.

    The nanostructures of strong and weak polyelectrolyte brushes in the ionic amphiphilic block copolymer monolayer at the air/water interface were investigated by in situ X-ray and neutron reflectometry. The hydrophilic layer under the water was found to be not a simple brush layer but a carpet/brush double layer structure when the hydrophilic chain is long enough and the brush density is high enough. The critical brush density and hydrophilic chain length for the transition between carpet only/ carpet + brush structure transition were also found. The weak acid monolayer first expanded by addition of salt but was shrunk by further addition of salt. The strong acid monolayer was not affected by salt addition up to certain salt concentration around 10(-1) M, but was shrunk by further addition of salt. These phenomena could be interpreted as due to the charged state of polyelectrolyte chains in the brush layer and the electrostatic repulsion between polymer brush chains in the brush layer.

    The effect of salt concentration on the nanostructure of a spread monolayer of ionic amphiphilic diblock copolymer, (diethylsilacyclobutane)(m)-b-(methtcrylic acid)(n), at the air-water interface was directly investigated by in situ X-ray reflectivity and neutron reflectivity techniques. Previously, we had found that a poly(methacrylic acid) (PMAA) hydrophilic layer under the water was not in the form of a simple polyelectrolyte brush but consisted of a dense carpet upper layer and a diffuse brush lower layer when the hydrophilic chain was long enough. Here we observed this double layer formation in the monolayer in aqueous NaCl solution at a constant surface pressure. The effect of salt added to the subphase differed with the salt concentrations, that is, below or above 0.1 M. In the presence of NaCl up to 0.1 M, both the hydrophobic layer and brush layer thicknesses decreased. On the other hand, both of them increased in the presence of NaCl above 0.1 M. Also, the carpet layer thickness was almost constant independent of the salt concentration. In addition, the brush top roughness showed a maximum in the presence of 0.1 M NaCl. The increase of the charge number on the PMAA chain and the screening effect of the Coulomb interaction by added salt ions were considered to be responsible for these phenomena.

    Detailed analysis of an interesting poly(methacrylic acid) (PMAA) brush structure in water of a diblock copolymer [(Et2SBm-b-(MMA)(n), where Et2SB is diethylsilacyclobutanel monolayer reported previously was performed by X-ray and neutron reflectometry and indicated that the hydrophilic layer formed with a relatively long PMAA chain is not a simple layer but is divided into two layers, that is, a "carpet"-like dense PMAA layer near the hydrophobic layer and a polyelectrolyte brush layer. The hydrophilic chain length dependence of the diblock copolymer monolayer was analyzed using m:n = 30:x polymer samples, especially of the PMAA double layer structure. With the increase in PMAA chain length in polymer samples, a carpet layer is mainly formed up to n similar to 50. With further increase in the PMAA chain length beyond n similar to 50, a well-defined brush layer appears. On the other hand, the variation in hydrophobic layer thickness with methacrylic acid unit is minimum at the critical PMAA length, that is, n similar to 50 under a constant surface pressure condition. It is strongly suggested that the two discrete layers contribute differently to surface pressure. Furthermore, from the comprehensive viewpoint, the major factor for brush formation was clarified not to be the absolute length of the PMAA chain, but the ratio of PEt2SB and PMAA chain length is an important factor.

    Sodium poly(styrenesulfonate)(polySSNa)-grafted polymer nanoparticles were synthesized by core-cross-linking of block copolymer micelles and subsequent chemical transformation. Block copolymers, poly(p-(n-methyl)silacyclobutyl)styrene-blockpoly(neopentyl p-styrenesulfonate)s, polySBS-b-polySSPen, were synthesized by nitroxy-mediated living radical polymerization. The block copolymers formed micelles (R-h=15-23 nm, where R-h represents the hydrodynamic radius) with a polySBS core and polySSPen shell in acetone. The micelle core was cross-linked by ring-opening polymerization of silacyclobutyl groups in polySBS. Hydrolysis of the neopentyl groups provided polySSNa-grafted nanoparticles. The Rh of the particles before the hydrolysis ranged from 12 to 21 nm in acetone, while they varied to the range from 50 to I 10 nm in water after the hydrolysis. (C) 2004 Elsevier Ltd.

    We synthesized an ionic amphiphilic diblock copolymer, poly(hydrogenated isoprene)-b-poly(styrenesulfonic acid) (PIp-h(2)-b-PSS), by living anionic polymerization, and the nanostructure of its monolayer spread on a water surface was directly investigated by the in situ X-ray reflectivity technique. The monolayer of the diblock copolymer on a water surface had a smooth hydrophobic PIp-h(2) layer on water and a "carpet"/ polymer brush double layer in a hydrophilic sodium polystyrene sulfonate (PSSNa) layer under the water. The surface pressure dependence and PSSNa chain length dependence of the PIp-h2 layer thickness and the brush nanostructure were quantitatively studied. The effect of salt concentration in the subphase was also investigated in aqueous solutions containing 0-2 M NaCl. The salt effect on monolayer structure occurred at around 0.2 M. The thickness of the PSS brush layer decreased at salt concentrations above 0.2 M, while no structural change was observed below 0.2 M. This critical salt concentration is thought to be related to the balance of ionic concentrations inside the brush and in bulk solution.

    Strongly ionized amphiphilic diblock copolymers of poly(styrene)-b-poly(styrenesulfonate) with various hydrophilic and hydrophobic chain lengths were synthesized by living radical polymerization, and their properties and self-assembling behavior were systematically investigated by surface tension measurement, foam formation, hydrophobic dye solubilization, X-ray reflectivity, dynamic light scattering, small-angle neutron scattering, small-angle X-ray scattering, and atomic force microscope techniques. These copolymer solutions in pure water did not show a decrease of surface tension with increasing polymer concentration. The solutions also did not show foam formation, and no adsorption at the air/water interface was confirmed by reflectivity experiments. However, in 0.5 M NaCl aq solutions polymer adsorption and foam formation were observed. The critical micelle concentration (cmc) was observed by the dye solubilization experiment in both the solutions with and without added salt, and by dynamic light scattering we confirmed the existence of polymer micelles in solution, even though there was no adsorption of polymer molecules at the water surface in the solution without salt. By the small-angle scattering technique, we confirmed that the micelles have a well-defined core-shell structure and their sizes were 100-150 Delta depending on the hydrophobic and hydrophilic chain length ratio. The micelle size and shape were unaffected by addition of up to 0.5 M salt. The absence of polymer adsorption at the water surface with micelle formation in a bulk solution, which is now known as a universal characteristic for strongly ionized amphiphilic block copolymers, was attributed to the image charge effect at the air/water interface due to the many charges on the hydrophilic segment.

Both polyNaMA-b-polyNFHMA and polyNaMA-b-polyHMA formed micelles above critical micelle concentrations, (cmc's), around 3 x 10(-5) to 1 x 10(-4) mol/L, while neither polymer decreased surface tension of aqueous solutions. The size and shape of the micelles were examined by dynamic light scattering, small-angle neutron scattering, and small-angle X-ray scattering. PolyNaMA-b-polyHAM appeared to form only spherical micelles, while polyNaMAb-polyNFHMA with a long NFHMA segment formed both spherical and rodlike micelles. The micelles of fluorine-containing block copolymers were obviously larger than those of non-fluorine-containing block copolymers with the same chain length and the same hydrophilic/hydrophobic chain ratio. The fluorine-containing block copolymer selectively solubilized fluorinated dye into the water phase when a mixture of decafluorobiphenyl and 2,6-dimethylnaphthalene was added to the micelle solution.

    Fluorine-containing amphiphilic block copolymers, poly(2-hydroxyethyl vinyl ether)-block-poly(2-(2,2,2-trifluoroethoxy)ethyl vinyl ether)) (poly(HOVE-b-TFEOVE) (m = 78, n = 23)), poly(2-hydroxyethyl vinyl ether)-block-poly(2-(2,2,3,3,3-pentafluoropropoxy)ethyl vinyl ether) (poly(HOVE-b-PFPOVE) (m = 74, n = 22)), and poly(2-hydroxyethyl vinyl ether)-block-poly(2-(2,2,3,3,4,4,4-heptafluorobutoxy)ethyl vinyl ether) (poly(HOVE-b-HFBOVE) (m = 79, n = 19)) were synthesized along with the non-fluorine-containing amphiphilic block copolymer, poly(2-hydroxyethyl vinyl ether)-block-poly(n-butyl vinyl ether) (poly(HOVE-b-NBVE) (m = 70, n = 22)), where m and n are polymerization degrees of hydrophilic segment and hydrophobic segment, respectively. These fluorine-containing block copolymers considerably reduced the surface tension of the aqueous solutions, indicating the high surface activity of the block copolymers. They formed core-shell rodlike and/or core-shell spherical micelles in aqueous solutions, which were evaluated by small-angle neutron scattering (SANS), small-angle X-ray scattering (SAXS), and dynamic light scattering (DLS) analyses. A qualitative trend was observed, that is, the fraction of rodlike micelles increased, as the number of fluorine atoms in a hydrophobic segment increased. The fluorine-containing block copolymer selectively solubilized the hydrophobic fluorinated dye into water phase and the fluorinated dye selectivity increased as the number of the fluorine atoms in the hydrophobic monomer unit increased. Solubilization of a low molecular weight compound strongly affected the copolymer micelle structure, which was also confirmed by SANS, SAXS, and DLS analyses.

    A carpetlike dense-layer formation between a hydrophobic layer and a polyelectrolyte brush layer has been found in the monolayers of an ionic amphiphilic diblock copolymer, poly(1,1-diethylsilacyclobutane)m-block-poly(methycrylic acid)n, on a water surface by an X-ray reflectivity technique. By detailed analysis, we have found that the hydrophilic layer under the water is not a simple layer but is divided into two layers, that is, a carpetlike dense methacrylic acid (MAA) layer near the hydrophobic layer and a polyelectrolyte brush layer. We have also confirmed that a well-established polyelectrolyte brush is formed only for the m:n = 43:81 polymer monolayer: For m:n = 40:10 and m:n = 45:60 polymer monolayers, only a dense MAA layer is formed. This dense-layer formation should be the origin of the interesting hydrophobic-layer thickness variation previously reported The hydrophobic-layer thickness takes a minimum as a function of the hydrophilic chain length at any surface pressure studied. An overview of the data for three samples with different chain lengths (m:n = 40:10, 45:60, or 43:81) has shown that the thickness of this dense layer is 10-20 Å and is independent of the surface pressure and polymerization degree of poly(methacrylic acid) (PMAA) in the range studied. This dense-layer formation is explained by the reasonable speculation that contact with PMAA is thermodynamically more stable than direct contact with water for diethylsilacyclobutane (Et2SB) layer on water. In this sense, the dense layer acts like a carpet for the hydrophobic Et2SB layer, and a 10-20-Å thickness could be a critical value for the carpet.

    A novel amphiphilic diblock copolymer having sulfonic acid groups in its hydrophilic chain with poly(diethylsilacyclobutane) as a hydrophobic segment was synthesized by living anionic polymerization followed by treatment with 1,3-propane sultone. The polymer backbone with a degree of polymerization of 18 (hydrophobic):37 (hydrophilic) was synthesized, and three kinds of diblock copolymers with different degrees of sulfonation (alpha = 0, 0.50, 0.81) were prepared as sodium salts. The surface tension of aqueous solutions of highly sulfonated polymers as including the alpha = 0 (all carboxylic acid) polymer did not decrease with polymer concentration. The solutions did not show foam formation even after vigorous shaking, and almost no adsorption of polymer molecules was observed at the air/water interface by X-ray reflectivity measurement. However, micelle formation with a radius of 140-200 Angstrom was confirmed by dynamic light scattering and small-angle X-ray scattering experiments. Hence, this polymer showed ''micelle formation'' without ''Gibbs monolayer formation'' in water. The surface tension decrease in 0.5 M NaCl aqueous solution was also small, but adsorption of polymer was observed by X-ray reflectivity in addition to formation of foam by shaking. The strong ionic character of this novel class of amphiphilic polymer is thought to be the origin of this curious behavior.

    Synthesis and anionic polymerization of silacyclopropane derivatives, 2-n-butyl-l-sec-butyl-1-tert-butylsilacyclopropane (1s1t2n-BuSP) and 2-n-butyl-1-tert-butyl-1-isobutylsilacyclopropane (1i1t2n-BuSP), were investigated. These monomers were prepared by treatment of sec-butyl-tert-butyldichloro-silane or tert-butylisobutyldichlorosilane with lithium in the presence of I-hexene. Monomers 1s1t2n-BuSP and 1i1t2n-BuSP could be polymerized with a butyllithium initiator in THF at -78 degreesC in the presence of hexamethylphosphoramide (HMPA). After precipitation in methanol, poly(2-n-butyl-1-sec-butyl-1-tert-butylsilacyclopropane) (poly(1s1t2n-BuSP)) (M-n = 2100, M-w/M-n = 1.53, relative to a polystyrene standard) and poly(2-n-butyl-1-tert-butyl-1-isobutylsilacyclopropane) (poly(1i1t2n-BuSP)) (M-n = 1800, M-w/M-n = 1.60) were obtained. Contact angles of water with poly(1s1t2n-BuSP) and poly(lilt2n-BuSP) were determined as 103 and 102degrees, respectively. This significantly high hydrophobicity is probably due to the unusually large number of methyl groups in the repeating unit.

    The nanostructure of a monolayer of the ionic amphiphilic diblock copolymer, poly(1,1-diethylsilacyclobutane)-blockpoly(methacrylic acid) (poly(Et2SB-b-MAA)) with different MAA chain lengths on water, was investigated at various pH by in-situ X-ray reflectometry. The monolayer nanostructure was similar in acidic and neutral conditions, but significantly different on the subphase of PH10, With the long MAA polymer a dense carpet layer was detectable, but the carpet/brush structure in the monolayer was not observed. The short MAA chain sample on the subphase of PH10 had an Et2SB layer in monolayer explicitly thicker than that in an acidic or neutral condition at the same surface pressure. The differences in monolayer nanostructure can be attributed to the difference in ionization condition of carboxylic groups in the MAA chain.

    Anionic amphiphilic diblock copolymers, poly(1,1-diethylsilacyclobutane)-block-poly(methacrylic acid) (poly(Et2SB-b-MAA)) and poly(alpha-methylstyrene)-block-poly(methacrylic acid) (poly(MeSt-b-MAA)), were synthesized, and the nanostructure of their spread monolayer on the water surface was investigated by direct in situ X-ray reflectivity (XR) measurement. XR profiles for the poly(Et2SB-b-MAA) monolayer showed many Kiessig fringes even though on a water surface, indicating the very smooth and flat surface and interfaces in the monolayer. On the other hand, the poly(MeSt-b-MAA) monolayer was suggested to have a larger surface roughness since no Kiessig fringe was observed in the XR profile. The XR profiles for the poly(Et2SB-b-MAA) monolayer clearly indicated that the polymers form monolayers consisting of two layers: a hydrophobic Et2SB upper layer and the hydrophilic MAA lower layer in the water subphase. The Kiessig fringe due to the overall layer including the MAA brush in the subphase was also observed for the copolymer with a longer MAA chain in addition to those for the Et2SB layer. The thickness and surface/interface roughness for the poly(Et2SB-b-MAA) monolayer at various surface pressures were evaluated by model fitting of XR curves. The thickness of the Et2SB layer increased continuously with increasing surface pressure, reflecting the very flexible nature of the Et2SB chain. The nanostructure of the poly(Et2SB-b-MAA) monolayer at the air/water interface was examined as a function of pH and MAA block length. Almost no change was found for monolayer nanostructures on HCl aq (pH = 2) and pure water as a subphase. The MAA length dependence of the thickness of the Et2SB layer showed an interesting tendency: it showed a minimum as a function of MAA length. This unexpected and interesting observation reflected the difference of the MAA "brush" structure under the water subphase.

    Amphiphilic block copolymers, poly(1,1-dimethylsilacyclobutane-block-2-hydroxyethyl methacrylate) (poly(DMSB-b-HEMA)), poly(1,1-diethylsilacyclobutane-b-2-hydroxyethyl methacrylate) (poly(DESB-b-HEMA)), and poly(1,1-dibutylsilacyclobutane-block-2-hydroxyethyl methacrylate) (poly(DBSB-b-HEMA)), were synthesized by a living anionic polymerization, and their self-assembled structures were investigated. Small-angle X-ray scattering (SAXS) analysis suggested that the block copolymers formed micelles in methanol and that the aggregation number of the micelles increased with the increase of polysilacyclobutane (polySB) content and number of carbon atoms in the alkyl groups on silicon. A remarkable temperature dependence of the micelle structure of poly(DMSB-b-HEMA) was observed. Small-angle neutron scattering (SANS) revealed that the block copolymer formed spherical micelle with a core-shell structure above room temperature and a disklike micelle below room temperature. The surface pressure-area per molecule (pi-A) isotherm of spread copolymer indicated that poly(SB-b-HEMA)s formed a thin layered film on the water surface. The pi-A isotherm of the poly(DMSB-b-HEMA) spread layer also exhibited a characteristic temperature dependence. Direct X-ray reflectivity (XR) measurement on the water surface indicated that the block copolymers formed a monolayer with uniform thickness and smooth interfaces at medium surface pressure around 30 mN/m. In the case of poly(DBSB-b-HEMA), on the other hand, it was supposed that another layer with a large thickness appeared in the monolayer at a higher surface pressure than 35 mN/m. Atomic force microscopy (AFM) measurement of poly(DBSB-b-HEMA) film deposited on a glass plate at that surface pressure supported the existence of a thicker layer in addition to monolayer.

    Fluorine-containing amphiphilic ABA triblock copolymers, poly(2-hydroxyethyl vinyl ether)-block-poly[2-(2,2,3,3,3-pentafluoropropoxy)ethyl vinyl ether]-block-poly(2-hydroxyethyl vinyl ether) [poly(HOVE-b-PFPOVE-b-HOVE)] (HFH), poly[2(2,2,3,3,3-pentafluoropropoxy)ethyl vinyl ether] -block-poly(2-hydroxyethyl vinyl ether)block -poly[2-(2,2,3,3,3-pentafluoropropoxy)ethyl vinyl ether] [poly(PFPOVE-b-HOVEb-PFPOVE)] (FHF), and poly(n-butyl vinyl ether)-block-poly(2-hydroxyethyl vinyl ether)-block-poly(n-butyl vinyl ether) [poly(NBVE-b-HOVE-b-NBVE)] (LHL), were synthesized, and their behavior in water was investigated. The aforementioned polymers were prepared by sequential living cationic polymerization of 2-acetoxyethyl vinyl ether (AcOVE) and PFPOVE or NBVE, followed by hydrolysis of acetyl groups in polyAcOVE. FHF and LHL formed a hydrogel in water, whereas HFH gave a homogeneous aqueous solution. In addition, the gel-forming concentration of FHF was much lower than that of corresponding LHL. Surface-tension measurements of the aqueous polymer solutions revealed that all the triblock copolymers synthesized formed micelles or aggregates above about 1.0 x 10(-4) mol/L. The surface tensions of HFH and FHF solutions above the critical micelle concentration were lower than those of LHL, indicating high surface activity of fluorine-containing triblock copolymers. Small-angle X-ray scattering measurements revealed that HFH formed a core-shell sperical micelle in 1 wt % aqueous solutions, whereas the other block copolymers caused more complicated assembly in the solutions.

    An amphiphilic block copolymer of silacyclobutane and methacrylic acid (MAA) was synthesized via a living anionic polymerization of 1,1-diethylsilacylcobutane (EtSB). Sequential addition of 1,1-diphenylethylene and t-butyl methacrylate (tBMA) to living poly(EtSB) in the presence of lithium chloride gave poly(EtSB-block-tBMA) with narrow molecular weight distributions. The t-butyl ester groups in the obtained polymer were readily hydrolyzed via heating in 1,4-dioxane in the presence of concentrated aqueous hydrochloric acid. The block copolymer with a short MAA segment was soluble in chloroform and insoluble in methanol and basic water, whereas the block copolymer with a long MAA segment was soluble in methanol and basic water and insoluble in chloroform. The block polymer (EtSB/tBMA = 45/60) formed a monolayer film on the water surface; this was confirmed by surface pressure measurement. (C) 2000 John Wiley & Sons, Inc.

By water surface tension measurements, the critical micelle concentrations (cmc's) of poly(HOVE-b-TFEOVE) and poly(HOVE-b-NBVE) were both estimated at 1.0 x 10(-4) mol/L. Solubilization of various fluoro and non-fluoro compounds using these polymer aqueous solutions was examined. It was confirmed that poly(HOVE-b-TFEOVE) solubilized more decafluorobiphenyl than did poly(HOVE-b-NBVE), whereas poly(HOVE-b-NBVE) solubilized more 2,6-dimethylnaphthalene than did poly(HOVE-b-TFEOVE). When a mixture of decafluorobiphenyl and 2,6-dimethylnaphthalene was added to the polymer: solutions, poly(HOVE-b-TFEOVE) selectively solubilized decafluorobiphenyl, while poly(HOVE-b-NBVE) solubilized 2,6-dimethylnaphthalene predominantly, which was observed by the UV absorption spectrum of the polymer solutions.

    Butyllithium-induced anionic ring-opening polymerization of phenyl-substituted silacyclobutanes was investigated. Polymerization of 1,1-dimethyl-3-phenylsilacyclobutane in tetrahydrofuran (TNF) at -78 degrees C proceeded in a living fashion. A linear relationship between In[M](0)/[M] and time ([M](0) is the initial concentration of the monomer and [M] is the concentration of monomer) and a linear relationship between number-average molecular weight (M(n)) and monomer conversion were observed. The molecular weight of the obtained polymer was very narrow (M(w)/M(n) = 1.09, M(w) is weight-average molecular weight). In contrast, neither 1,1-dimethyl-2-phenylsilacyclobutane nor 1-methyl-1-phenylsilacyclobutane showed a living nature under the game polymerization conditions, which were confirmed by two-step monomer addition experiments. (13)C NMR and (29)Si NMR spectrum of the poly(1,1-dimethyl-2-phenylsilacyclobutane) indicated that polymerization of 1,1-dimethyl-2-phenylsilacyclobutane proceeded without regioselectivity.

The surface tension of the polymer aqueous solution decreased to ca. 30 mN/m at polymer concentrations around 1 x 10(-4) mol/L. SAXS measurement of the aqueous polymer solution revealed that the polymers formed core-shelled spherical micelles at concentrations of 1.0 wt %.

    A spread monolayer of the amphiphilic block polymer poly(1,1-diethylsilabutane)-block-poly(2-hydroxyethyl methacrylate) (poly(SB-b-HEMA)) on the water surface was investigated by X-ray reflectivity (XR) measurements. Clear Kiessig fringes were observed up to the third order in the XR curve. This observation means the formation of the smooth-faced monolayer with high uniformity of thickness. The thickness of the monolayer increased with increasing surface pressure. Model filling with the two-layer model revealed that the upper layer is formed by the melt of the SE chains and that the lower layer consists of hydrated HEMA chains. The flexibility of the SE chain is thought to be an origin for the formation of the smooth, dense, and variable-thickness polymer monolayer on the water surface.

    Amphiphilic diblock polymers having an octadecyl group as a hydrophobic segment with different degrees of polymerization were synthesized by living cationic polymerization. Matrix-assisted laser desorption-ionization time-of-flight mass spectrometry (MALDI TOF MS) was performed to determine the molecular weight. Differential scanning calorimetry (DSC) measurements for polymer solid samples showed the melting point depending on the degree of polymerization. The size and shape of micelles formed by the polymers in water were investigated by small-angle X-ray scattering (SAXS) and neutron scattering (SANS) measurements. The aggregation number reduced with increasing degree of polymerization, while the overall micelle size was almost independent. The SAXS and SANS data revealed the sphere-to-disk transition on changing temperature for the polymer with the shortest hydrophilic chain. Below the melting point of hydrophobic chain, the polymer formed disklike aggregates with a crystallized core of octadecyl groups surrounded by a swollen shell. With increasing temperature, octadecyl groups melted and the spherical micelle formed.

    Aggregation behavior of a novel amphiphilic polycarbosilane block copolymer was investigated. Polystyrene-h-poly(3-hydroxymethylsilacyclobutane) (PSt-b-PHMSB) was synthesized by sequential anionic block polymerization of styrene with 1, 1-dimethyl-3-methylenesilacyclobutane in benzene at room temperature, followed by hydroboration-oxidation of C-C double bonds. PSt-b-PHMSB was soluble in a nonpolar solvent such as toluene and polar solvent such as methanol. From the results of small-angle X-ray scattering (SAXS) measurement of the polymer solution, it was suggested that the amphiphilic polymer formed aggregates like micelles in toluene and methanol.

Poly(1,1-diethylsilabutane)-b-poly(methy methacrylate) was obtained by treatment of living poly(1,1-diethylsilabutane) with 1,1-diphenylethylene followed by an addition of methyl methacrylate. Poly(1,1-diethylsilabutane)-b-poly(2-(tert-butyldimethylsiloxy)ethyl methacrylate) was also synthesized by adding 2-(tert-butyldimethylsiloxy)ethyl methacrylate to the living poly(1,1-diethylsilabutane) which was end-capped with 1,1-diphenylethylene in the presence of lithium chloride.

    A new class of polar polysilabutanes with mono- or tri-(oxyethylene) phenyl groups on the silicon atom have been synthesized by anionic polymerization of silacyclobutanes having omega-(t-butyldimethylsilyl-protected) mono-or tri-(oxyethylene)phenyl groups and subsequent deprotection of the silyl groups. The monomers were synthesized by treatment of I,1-dichlorosilacyclobutane with omega-(t-butyldimethylsilyl-protected) mono-or tri-(oxyethylene) phenyl Grignard reagents. Anionic polymerization of silacyclobutane was performed with butyllithium initiator in THF. t-Butyldimethylsilyl-protecting groups at polymer pendant groups were hydrolyzed with tetrabutyl ammonium fluoride in water-containing THF. The obtained polysilabutanes were soluble in a polar organic solvent such as methanol, and their mass distributions were analysed by matrix-assisted laser-desorption-ionization mass spectrometry (MALDI TOF MS).

    Anionic polymerizations of 1,1-dimethylsilacyclobutane, 1,1-diethylsilacyclobutane and 1-methyl-1-phenylsilacyclobutane were investigated. Addition of 5 mol % of butyllithium to a solution of 1,1-dimethylsilacyclobutane in THF-hexane (1 : 1) at -48 degrees C provided poly(1,1-dimethylsilabutane) in 99% yield. M-n and M-w/M-n of the obtained polymer were 2400 and 1.10. This polymerization proceeded with a living nature. M-n increased in proportion as the yield of polymer increased. Addition of the second fresh feed of the monomer to the reaction mixture restarted polymerization of the second monomer at the same rate as in the initial stage. Addition of styrene to the living poly(1,1-dimethylsilabutane) provided a poly(1,1-dimethylsilabutane-b-styrene) block copolymer. It was also found that a polymerization of 1,1-diethylsilacyclobutane in THF-hexane at -48 degrees C showed a living nature. In contrast, a polymerization of 1-methyl-1-phenylsilacyclobutane in THF at -78 degrees C did not show a living nature. (C) 1997 John Wiley & Sons, Inc.

    Synthesis of polysilabutane-block-poly (vinyl alcohol) amphiphilic block copolymer was investigated. Poly (1, 1-dimethylsilabutane) having dimethyl acetal group at the polymer end was synthesized by anionic ring-opening polymerization of 1, 1-dimethylsilacyclobutane in tetrahydrofuran (THF) -hexane-48°C, using 3-lithiobenzaldehyde dimethy acetal as an initiator. The dimethyl acetal group at the polymer end was converted into the formyl group by hydrolysis. Poly (1, 1-dimethylsilabutane) -block-poly (t-butyldimethylsilyl vinyl ether) was prepared by aldol group transfer polymerization (Aldol GTP) of t-butyldimethylsilyl vinyl ether using poly (1, 1-dimethylsilabutane) as a macro initiator. On hydrolysis of silyl ether groups of the polymer, polysilabutane-block-poly (vinyl alcohol) was obtained.

    Treatment of 3-methylene-1,1-diphenylsilacyclobutane (1a) with dihalo-melhyllithium provided ring expanded 2-halo-4-methylenesilacyclopentane. Heating a mixture of 1a and carbonyl compound such as PhCHO or PhCOMe at reflux in 1,2-dichloroethane afforded 5 methylene 1,1 diphenyl-2-oxa-1-silacyclohexane which was converted into 3-methylene-1,5-alkanediol monomethyl ether upon treatment with dimethyl acelal in the presence of Lewis acid catalyst. Treatment of ketoaldehyde (PhCOCH2CHO) with 1a under BF3· OEt2 catalysis gave 3-methylene-1-phenyl-8 oxabicyclo[3.2.1]octane in one pot. © 1995.

    Two methods for ring enlargement of silacyclobutane into silacyclopentane have been described. (1) Treatment of 1-(1-iodoalkyl)silacyclobutane with t-BuOK or AgOAc provided 2-alkyl-1-silacyclopentanes which were easily converted into 1,4-diols by oxidative cleavage of carbon-silicon bond. (2) An addition of i-PrOLi to 1-[(Z)-1,2-epoxyhexyl]-1-methylsilacyclobutane gave erythro-2-(1-hydroxypentyl)-1-isopropoxy-1-methylsilacyclopentane, which was converted into (Z)-4-nonen-1-ol, (E)-4-nonen-1-ol, or 1,4,5-nonanetriol.

    Treatment of 2-(trimethylsilyl)silacyclopentane with t-butyllithium in THF-HMPA gave 2-lithio-2-(trimethylsilyl) silacyclopentane in good yield. An addition of alkyl iodides to the lithium compound provided 2-alkyl-2-trimethylsilyl)silacyclopentanes which were converted into 1-alkyl-1,4-butanediols upon treatment with H2O2-KF and successively with n-BU4NF. Reaction of 2-lithio-2-(trimethylsilyl)silacyclopentane with aldehydes gave 2-alkylidenesilacyclopentaiies, which were transformed into gamma-hydroxy ketones by oxidative cleavage of carbon-silicon bonds. 2-Lithio-2-(phenylthio)silacyclopentane, derived from 2-(phenylthio)silacyclopentane and t-butyllithium, afforded alkenyl sulfides having silylalkyl substituent upon treatment with aldehydes. Oxidative cleavage of carbon-silicon bonds followed by hydrolysis of alkenyl sulfide moiety also provided gamma-hydroxy ketones.

    エポキシ樹脂などの熱硬化性樹脂は物性に優れた樹脂硬化物を与えることから広くに利用されているが、安定な3次元網目状の分子構造を形成するため分解性に乏しく廃棄時には問題となる。また、多くの樹脂は石油由来原料から合成されるため、資源枯渇やCO2排出量増大などの問題が懸念される。1分子に複数の5員環カーボナート基を持つカーボナート樹脂はエポキシ樹脂にCO2を吸収させることで合成でき、ジアミン類との反応によりヒドロキシウレタン系の硬化物となり、さらに高温に加熱すると分子内の水酸基により逆反応が進行して容易に分解できることから環境調和型の樹脂となり得る。今年度は、生物由来物質チラミンを用いて5員環カーボナート樹脂を合成し、硬化反応および硬化物の物性検討を行った。 チラミン、エピピクロロヒドリン、ベンジルトリエチルアンモニウムクロリド(触媒)を40℃に加熱後、水酸化ナトリウム水溶液を作用させ、ジエチルエーテル/水で後処理、濃縮、シリカゲルカラムクロマトグラフィーで精製してチラミントリエポキシド(TTE)を得た。TTEのN,N-ジメチルホルムアミド溶液にLiBr触媒を加えCO2雰囲気下100℃に加熱後、反応液を酢酸エチル/水で後処理、濃縮、真空乾燥しチラミントリカーボナート(TTC)を得た。TTCに1.0当量の4,7,10-トリオキサ-1,13-トリデカンジアミン(TODA)を添加し2枚のテフロン基板間に挟み150℃で1時間加熱した結果、均質で丈夫な硬化物フィルムが得られた。IR測定によりジアミンの付加反応が完結していることが確認できた。示差走査熱量分析、熱重量分析、引張試験の結果、ガラス転移温度-2℃、5%重量減少温度223℃、破断強度2.2MPa、破断伸び1.2が求まり、得られた硬化物は比較的低い熱分解温度を示す易分解性の材料で室温で柔軟かつ強靭なゴム状材料あることがわかった。

    ペンタフルオロスチレン(PFS)とp-(1-メチルシラシクロブチル)スチレン(SBS)の9/1混合物をモノマーとしてニトロキシ制御ラジカル重合を行い、さらに、ネオペンチルスチレンスルホン酸(SSPen)を重合させることで、架橋可能なジブロックコポリマー(PFS_<0.9>-co-SBS_<0.1>)_<123>-b-SSPen_<44>を合成した。各セグメントの重合度はポリスチレン換算のGPC測定により、PFSとSBSの組成比は^1H-NMR測定により決定した。このポリマーは、アセトニトリル中で(PFS_<0.9>-co-SBS_<0.1>)_<123>セグメントをコアとするミセルを形成した。このミセル溶液に白金系触媒を作用させたところ、ミセルコア内でSBSの開環重合が進行し、架橋ミセルCCL(PFS_<0.9>-co-SBS_<0.1>)_<123>-b-SSPen_<44>が得られた。ここにヨウ化トリメチルシリルを作用させ、塩酸で処理し水酸化ナトリウム水溶液で中和することでスルホン酸エステルを加水分解してSSPenセグメントをスチレンスルホン酸ナトリウム(SSNa)セグメントに変換し加水分解架橋ミセルCCL-(PFS_<0.9>-co-SBS_<0.1>)_<123>-b-SSNa_<44>を得た。スルホン酸エステルの加水分解の進行はIRにより確認した。加水分解架橋ミセルは、水に対して可溶であった。ブロックコポリマーミセル、架橋ミセル、加水分解架橋ミセルの粒径を動的光散乱により評価したところ、それぞれ、116nm、122nm、164nmと求まった。さらに、CCL-(PFS_<0.9>-co-SBS_<0.1>)_<123>-b-SSNa_<44>の水溶液をガラス基板上で乾燥させて原子間力顕微鏡により観察したところ、直径150nm程度の球状粒子が多数確認できた。以上のように、本研究により含フッ素ポリマーでできた水溶性超微粒子を合成する手法を確立することができた。

    Molecular properties and self-assemblies, such as micelle in water and monolayer at the air/water interface, of ionic amphiphilic diblock copolymers were systematically investigated from synthesis to nanostructure analysis. Unexpectedly, the ionic amphiphilic block copolymers shows "non-surface activity" but forms micelles in solution. Since this phenomenon is out of commonsense of surface and interface science, this polymer can be regarded as a novel substance. By investigation with block copolymer with various chain length and length ratios, the origin of the non-surface activity could be attributed to the image charge effect at the air/water interface, and the requirements to be non-surface active were quantitatively clarified. The non-surface activity is achieved by the accurate balance of three factors, polymerity, ionicity, and hydrophobicity. The polymer micelle in water shows extremely high toughness against salt addition. No aggregates were formed up to 0.5M NaCl. The structure transition between spherical and rod-like micelles were also observed as a function of chain length and salt concentration. The nanostructure of their polymer monolayer on the water surface was systematically investigated by X-ray and neutron reflectivity techniques. The monolayer structure is not a simple double layer of hydrophobic and hydrophilic brush layers, but is triple layer with "carpet" layer between them. The carpet layer is dense hydrophilic layer, whose thickness is almost constant at 15Å. The critical brush density for the transition between double and triple layer structures could be estimated. Also, the critical salt concentration, where nanostructure change occurs by salt addition, was found to be in the order of 10^<-1>M salt. In conclusion, the properties and self-assembling behavior of "novel substance", ionic amphiphilic diblock copolymer, could be clarified by the fusion of high techniques for precession synthesis of amphiphilic polymers and for nanostructure analysis with scattering and reflectivity.

    To detect and clariy the specific dynamics in polymers at interfaces, especially polymer monolayer on water surface, we have developed a novel instrument, Surface Dynamic Light Scattering (SDLS). First, we investigated the nanostructure of polymer monolayer on water by utilizing X-ray reflectometrer. The polymer used for monolayer preparation was poly (silacyclobutane)- b-poly(methacrylic acid), which was synthesized in our laboratory. As a result, we found that the hydrophilic layer under water surface is not a simple brush layer but it composed of two layers, i.e. carpet-like layer with high polymer density and polymer brush layer. The carpet layer is thought to be formed to avoid contact between hydrophobia layer and water. Its thickness was almost 15Å independent the polymer chain length and surface pressure. This is a quite novel finding. The brush layer became thicker under high pH condition. Also, salt effect for brush layer structure was also investigated. SDLS instrument was designed with the principle of heterodyne optical system. By a try-and-error, we found that a beam splitting by grating is the best method for SDLS optics. Next, we found that the small vibration of the instrument table has a large effect for SDLS data. Hence, we introduced an active vibration-isolation table for instrument, and it was confirmed that this arrangement is fine for our purpose. A piezo-insulator was installed in the instrument to produce a small artificial wave on water surface system. Typical amplitude was 1 micrometer and the typical frequency was in the range of 100-300 Hz. This surface wave was clearly detected by our SDLS and we obtained the time correlation function with oscillation. This oscillation is a response from polymer monolayer on water. When the frequency 100Hz was added, we observed response frequency at 100, 200, 300 Hz. However, when 200Hz wave was added by piezo, only 100Hz response was observed. This means that the polymer monolayer has a characteristic viscoelasticity. Hence it was confirmed that the SDLS instrument we have developed can be used to obtain quantitative information for monolayer on water surface.

    本研究では、フッ素ポリマーとケイ素ポリマーの両方の特性を生かした新しい機能性材料の開発を目指し、フルオロアルキル基をケイ素上に有するシラシクロブタンモノマーの合成、重合、および生成ポリマーの性質に関して検討を行った。得られた成果を以下に示す。 (1)ジエチルエーテル中-78℃で1,1-ジクロロシラシクロブタンとヨウ化ペルフルオロアルキルの混合物に2等量のメチルリチウムを作用させると、1-メチル-1-ペルフルオロアルキルシラシクロブタンが得られることを見いだした。また、同様に1-クロロ-1-フェニルシラシクロブタンとヨウ化ペルフルオロアルキルの混合物に1等量のメチルリチウムを作用させると、1-フェニル-1-ペルフルオロアルキルシラシクロブタンが得られることを見いだした。 (2)1-メチル-1-ペルフルオロアルキルシラシクロブタンは、RhCl(PPh_3)_3を触媒として用いると100℃で重合し含フッ素ポリカルボシランを与えるが、同条件で1-フェニル-1-ペルフルオロアルキルシラシクロブタンは、全く重合しないことがわかった。溶媒は、テトラヒドロフランが適しており、1,4-ジオキサンやトルエン、ベンゼン等は、重合の進行を著しく阻害することが明らかとなった。また、白金やパラジウム等の遷移金属には、触媒活性がないことがわかった。 (3)含フッ素ポリカルボシランは、ヘキサフルオロベンゼン等のフッ素系溶媒やジエチルエーテルに高い溶解性を示した。しかしながら、クロロホルムやトルエン、ベンゼン等の汎用の無極性有機溶媒には不溶であった。また、生成したポリマーのガラス転移温度は、-37℃であり、極めて柔軟なポリマーであることが明らかとなった。さらに、ポリマー薄膜と水との接触角は、97゜であり、極めて疎水性の高いポリマーであることがわかった。

    Self-assembly of novel amphiphilic polymers containing silicon or fluorine atoms were investigated in detail. Small angle X-ray and neutron scattering techniques were employed for the analysis of the polymer aggregates in solution and X-ray reflectivity measurements were applied to the study of the polymer monolayers at the air-water interface. A comb-like amphiphilic polysilacyclobutane (SB) with hydrophilic polyoxyethylene side chains dissolved as a single molecule in methanol or water. contrast, a 1 : 1 block copolymer composed of hydrophobic SB and hydrophilic 2-hydroxyethyl methacrylate (HEMA) or a 1 : 1 block copolymer composed of hydrophobic polystyrene and hydrophilic poly (3-hydroxymethylsilacyclobutane) formed micelles with hydrophobic core in methanol. Similarly they formed reversed-micelles with hydrophilic core in toluene. A 1 : 1 block copolymer composed of SB and HEMA formed uniform and stable monolayer at the water surface. A water-soluble vinyl ether block copolymer consisting of a short water-insoluble fluorinated segment and a long water-soluble polar segment formed core-shelled micelles in water as in the same way of non-fluorinated block copolymers. It is worth noting that the micelles formed by the fluorine-containing block copolymer could selectively solubilize fluorinated compounds from the mixture of fluorinated and non-fluorinated water-insoluble compounds. These results provided useful and important information for the evaluation of the hydrophilic-hydrophobic interaction of amphiphilic polymers.

    シラシクロブタンは、合成が容易である一方、環による大きな歪みエネルギーを持ち反応性に富む化合物である。我々は、有機リチウムを重合開始剤として用いると1,1-ジアルキルシラシクロブタンがリビング的に重合することを見いだし、カルボシラン系両親媒性ブロックポリマーの合成に応用した。1,1-ジエチルシラシクロブタンのリビングポリマーにジフェニルエチレンを加えて成長末端の反応性を制御した後、シリル基で保護したメタクリル酸2-ヒドロキシエチル(HEMA)を作用させてブロック共重合を行い、さらに加水分解を行うことにより含ケイ素両親媒性コポリマーpoly(SB-b-HEMA)を合成した。このポリマーのメタノール溶液中における会合挙動を小角X線散乱(SAXS)法によって観測した。その結果、ミセルが球状のコア-シェル構造を形成することが強く示唆された。また、疎水鎖長の増大に伴いミセルの会合数が増加することが明らかとなった。さらに、poly(SB-b-HEMA)(26:24)のポリマーのメタノール/トルエン混合溶液についてSAXS測定を行った結果、ミセルの形状は混合比に依存して変化し、トルエンrichな溶液では、コアとシェルの構成成分が反転し、逆ミセルが形成されることがわかった。さらに、poly(SB-b-HEMA)(26:24)のポリマーが作る単分子層を圧縮しながらX線反射率(XR)測定を行った。その結果、単分子層の表面、疎水部-親水部界面、および単分子層-水層間界面から反射したX線が干渉することによって生ずるKiessig fringeが観測され、このfringeは圧縮が進むとともに小角側にシフトし、圧縮によって単分子層の厚さが増加することが明らかとなった。

    本研究においては、ケイ素-炭素結合を主鎖骨格に有する構造と組成が厳密に制御されたポリカルボシラン系両親媒性高分子を合成する方法を開発すると同時に、これらの高分子を用いて溶液中における含ケイ素高分子鎖の挙動を追跡することにより、ナノ構造体への組織化機構に関する知見を得ることを目的として検討した。 反応性高分子として様々なポリマーへの変換が可能となる活性エキソメチレン基を繰り返し単位に有するポリアリルシランを合成するために、種々の3-メチレンシラシクロブタン誘導体のアニオン開環重合を検討し、対応するポリ(3-メチレンシラブタン)調製した。さらに、得られたポリマーをヒドロホウ素化、酸化することにより、ポリ(3-ヒドロキシメチルシラブタン)が得られることを見いだし、この内、1,1-ジメチル体は無極性溶媒には不溶で、極性溶媒に可溶であることことから、本法が極性ポリカルボシランの合成に有用であることが示された。 上述の重合反応を用いてブロックポリマーの合成を試みた結果、ポリ(1,1-ジメチルシラブタン-b-スチレン)ブロックコポリマー、およびポリ(1,1-ジメチルシラブタン-b-1,1-ジメチル-3-メチレンシラブタン)ブロックコポリマーが得られることを見いだした。生成ブロックポリマーは、ポリ(3-メチレンシラブタン)部分をヒドロホウ素化、酸化することにより疎水性および親水性セグメントからなる両親媒性ポリマーへ変換が可能となった。 ポリカルボシランの側鎖にオリゴオキシエチレン鎖を導入することにより極性ポリカルボシランを合成し、その溶液中での挙動を調査した。得られたポリマーは、メタノールなどの極性溶媒に可溶であり、その溶液のX線小角散乱を測定し解析したところ、ポリカルボシランがメタノール中で回転楕円体状の異方性の高い会合体を形成していることがわかった。

    The construction of the evanescent wave light scattering microscope (EVLSM) proved successful by the use of a novel technique combining the evanescent wave and the dynamic light scattering techniques. The dynamic and static characteristics of a polystyrene latex particle in dispersion interacting with a glass surface were studied by this technique. The dynamic behavior of the thermal vibration of the particle in a potential well created by electrostatic interaction between the particle and glass and gravity was clearly and quantitatively estimated, in addition to the estimation of the potential profile itself. The potential minimum became shallower with increasing added salt concentration, It was also clearly observed that the vibrational motion of the particle in the well became large in amplitude and the probability of the occurrence of the large vibration became large with increasing salt concentration. The potential profile of interaction between a charged liposome particle and glass surface was futhermore estimated directly by EVLSM, which can measure the distance between the particle and surface as a function of time at intervals in the order of less than ins, This new EVLSM technique was as well applied to the system between polystyrene latex particle and chemically-modified glass surface. Such information on the dynamics is essential for the correct understanding of the interaction potential. The EVLSM method is shown to be a very powerful technique for the estimation of not only the potential profilebut also dynamic characteristics.

    シラシクロブタンは、合成が容易である一方、環による大きな歪みエネルギーを持ち反応性に富む化合物である。これまでに、多くの重合反応が研究されてきた。しかしながら、分子量と分子量分布を精密に制御した重合法は見いだされていなかった。私は、シラシクロブタン誘導体のアニオン重合反応を詳細に検討した結果、1,1-ジメチルシラシクロブタンのテトラヒドロフラン-ヘキサン混合溶媒中-48℃で重合開始剤としてブチルリチウムを用いて重合を行うと、1,1-ジメチルシラシクロブタンがリビング的に重合することを見いだした。この重合反応は、様々な含ケイ素ブロックポリマーの合成に応用可能である。まず、1,1-ジメチルシラシクロブタンを重合させた後、反応系にスチレンを添加することによりポリ(1,1-ジメチルシラブタン-b-スチレン)ブロックコポリマーが得られることがわかった。ブロックポリマーの生成は、スチレン添加前後のポリマーのGPC測定により確認できた。このブロックポリマーの合成には、1,1-ジメチルシラシクロブタンの重合の後にスチレンを重合させることが重要で、モノマーの添加順を逆にするとブロックポリマーを効率良く合成することはできない。これは、スチレンの重合成長末端がシラシクロブタンのそれよりも安定であることによると考えられる。さらに、他のシラシクロブタン誘導体についてアニオン重合反応性を検討したところ、1,1-ジフェニルシラシクロブタンや1-メチル-1-フェニルシラシクブタンは、それぞれ分子量分布の狭いポリシラブタンを与えるが、重合反応がリビング反応性を示さないのに対して、1,1-ジエチルシラシクロブタンは、重合反応がリビング反応性を示すことがわかった。

    これまでに、親水性基を持つポリカルボシランの性質はほとんど知られておらず、極性ポリカルボシランの合成およびその溶液中での乳化やミセル化挙動に関する研究が極めて重要であると考えられる。 そこでまず、我々は、3‐メチレンシラシクロブタン誘導体のアニオン開環重合を検討した。その結果、テトラヒドロフラン中-78℃でブチルリチウムを開始剤として作用させると、ポリ(3‐メチレンシラブタン)を与えることを見いだした。得られたポリマーは、容易にポリ(3‐ヒドロキシメチルシラブタン)に変換できることを見いだした。この3‐メチレンシラシクロブタンと1,1‐ジメチルシラシクロブタンのブロック共重合を検討した結果、ポリ(1,1‐ジメチルシラブタン‐b‐1,1‐ジメチル‐3‐メチレンシラブタン)ブロックコポリマーが得られることを見いだした。生成ブロックポリマーは疎水性セグメントと親水性セグメントからなる両親媒性ポリマーへ変換することが可能で、溶液中でナノ組織体の形成が期待できる。また、我々は、オリゴオキシエチレン側鎖を持つシラシクロブタンのアニオン開環重合により、極性ポリカルボシランを合成し、その溶液中での挙動を調査した。その結果、得られたポリマーは、メタノールなどの極性溶媒に可溶であり、その溶液のX線小角散乱(SAXS)を測定し、解析したところ、ポリカルボシランがメタノール中で回転楕円体状の異方性の高い会合体を形成していることを見いだした。

    The purpose of this study is to accumulate the fundamental information for design and synthesis of advanced composites usable in cryogenic environments, From the results obtained in experiments of the first year, it is suggested that the polymers which are able to change the bond angles of the main chain seem to excel in cryogenic properties. This is partly because, even when their segmental motions are frozen out at cryogenic temperatures, these polymers could undergo deformation, and hence could still be flexible by changing the mainchain bond angles. In the experiments of the second year, the relationship between the crystallinity of polymers and the cryogenic properties was studied. The strength and the elongation at break point of polyphenylene sulfide at 77 K increase with an increase in the degree of crystallinity, In the case of polyethylene naphthalate, however, both mechanical properties at 77 K decrease with increasing the degree of crystallinity. These results indicate that the morphology of polymers greatly affects their cryogenic properties. Several properties of polymer composites are dependent on large number of factors such as resin content, relative flexibility of the matrix system, curing temperature and pressure, cure and post-cure cycle, as well as surface treatment of fibers. These findings offer us the useful information for developing the new type of advanced composites for cryogenic applications.
