An acid-functionalized dialkoxy biphenyl mesogen (LC-4,6A) was mixed to varying proportions with linear poly(ethylene imine) (PEI). Infrared analysis indicates that extensive complexation occurs in these blends, primarily via proton transfer that lea

The liquidcrystalline thermotropic behaviour of a series of long alkyl chain dimethylammonioalkoxydicyanoethenolates of the type CH3-(CH2)n-1-N+(CH3)2-(CH2)p-O-CO-C-(CN)2 (n=10-18, even values only, with p=2, 3; p=4 for n=16) was analysed through dif

The evidence for biphasic morphology in lightly sulfonated polystyrene (PS-SSA) ionomers neutralized by bifunctional organic cations (namely, 1,6-hexanediamine or HDA) is established by comparing their dynamic mechanical behaviors as a function of io

Blends of poly(2,6-dimethyl 1,4-phenylene oxide) (PPhO) with the copolymer poly(styrene-co-methacrylic acid) (PS-MAA) and the ionomer poly(styrene-co-sodium methacrylate) (PS-MAA-Na), up to 10 mol% co-unit content, were investigated by dynamic mechan

A solid-state NMR study of mixtures of poly(ethyl acrylate) (PEA) or poly(ethyl acrylate-co-sodium acrylate) (PEA-i) with sodium palmitate (SP) shows that (1) there is a change in the electron density of the carboxylate carbons of SP in the mixtures

A high molecular weight styrene ionomer containing 5 mol% sodium methacrylate was blended with a styrene oligomer (MW 800) and investigated by dynamic mechanical techniques. The focus of the study is on the dynamic melt rheology of these materials, w

The dynamic melt rheology of random copolymers of polystyrene with 2–9 mol% 4-vinylpyridine was examined in their quaternized and nonquaternized forms. Time–temperature reducibility applies in all cases. Relative to the glass transition, the mast

Structures of the thermotropic mesophases of lead(II) decanoate are reassigned following optical and X-ray diffraction studies. These results, and those of D.S.C., Raman and 207Pb N.M.R. spectroscopy, indicate formation of a lower temperature mesopha
