    Notes: The miscibility of poly (styrene-co-4-vinylphenyldimethylsilanol) (ST-VPDMS) and poly (n-butyl methacrylate) (PBMA) blends has been investigated by means of DSC and FT-IR spectroscopy. It was found that miscible blends were formed only for the copolymers containing 9-34 mol % 4-vinylphenyldimethylsilanol (VPDMS). The glass transition behavior of the miscible blends was analyzed by recently proposed equations in terms of the physical meaning of the fitting parameters. The results of FT-IR study were found to be fully consistent with the observation of the miscibility window obtained from glass transition temperature measurements. Quantitative information concerning intermolecular hydrogen bond interaction in the carbonyl stretching vibration region of the miscible blends was obtained by curve-fitting method. © 1994 John Wiley & Sons, Inc.

    Notes: Polymer blends consisting of poly(styrene-co-4-vinylphenylmethylphenylsilanol) (ST-VPMPS) and poly(n-butyl methacrylate) (PBMA) have been investigated. The experimental results showed that miscible blends were formed when ST-VPMPS copolymers contained 9-56 mol % silanol functional groups. Comparison of the results with poly(styrene-co-4-vinylphenyldimethylsilanol) (ST-VPDMS)/PBMA blends revealed that the miscibility window was shifted to a higher silanol composition in the present system in which a stronger hetero-associated hydrogen bonding interaction was present. The results were discussed in terms of steric shielding and electron-withdrawing effects of the phenyl substituent bound directly to the silicon atom. © 1996 John Wiley & Sons, Inc.

    Notes: The miscibility window of the 50/50 w/w poly(styrene-co-4-vinylphenyl)-dimethylsilanol/poly(n-butyl methacrylate) (ST-VPDMS/PBMA) blends prepared from toluene was studied and determined to be in the VPDMS composition range of 4 to 18 mole% in the copolymers. The observed miscibility window was to be compared to the range of 9 to 34 mole% found for the blends prepared from methyl ethyl ketone which was capable of competing for hydrogen bonding. The fact that the observed miscibility windows are influenced by the choice of solvents illustrates that an equilibrium state of polymer mixing is not always attained in solvent casting films and that caution needs to be exercised in studying polymer miscibility when solvent cast films are used.

    Notes: Polymer blends of poly(N-vinylpyrrolidone) (PVPr) and poly(styrene-co-4-vinylphenylmethylphenylsilanol) (ST-VPMPS) copolymers with varying amounts of VPMPS monomer units have been investigated. Glass transition temperature (Tg) measurements indicated that miscible blends of PVPr with ST-VPMPS copolymers were formed when the copolymers contained 9 mole% VPMPS or more. In addition, precipitated interpolymer complexes were formed from solution blending when the copolymer contained 31 mole% VPMPS or more. Enhanced Tgs were found for most miscible blends. Fourier transform infrared spectroscopy studies revealed that the hetero-associated hydrogen bond between the silanol and amide carbonyl groups was stronger than that of the silanol self-associated hydrogen bonds of the copolymers. Tg comparisons of the ST-VPMPS/PVPr miscible blends with the previously reported poly(styrene-co-4-vinylphenyldimethylsilanol) and PVPr (ST-VPMPS/PVPr) miscible blends were made. The enhanced Tgs of the miscible ST-VPMPS/PVPr blends were attributed to a close-packed hetero interpolymer chain segments associated with the “free volume” changes due to the formation of strong hetero-associated hydrogen bond.

    Notes: Miscible blends through hydrogen bonding have been intensively studied. The effects of a variety of miscible hydrogen bonded polymer blends on properties such as thermal and thermal oxidative stability, moisture sensitivity, modulus and glass transition temperature are discussed. In addition, the preparation of semi-interpenetrating polymer networks (IPNs) and studies of the effect of crosslinking on the miscibility in hydrogen bonded polymer blends are reviewed.
