Styrene-p-chlorostyrene) triblock copolymers of the ABA and BAB types (A--polystyrene; B--poly-p-chlorostyrene) were prepared by anionic polymerization and their conformational behaviours in solutions were studied from measurements of the dipole moments. Two solvents, toluene and cumene, were used f

Viscosity measurements on poly-p-chlorostyrene (PPCS) in benzene-methanol mixtures have been carried out at their corresponding theta temperatures determined by the phase separation method. Viscosity measurements were also run in benzene at the same temperatures. The Stockmayer-Fixman extrapolation
The mean-square dipole moments of poly(dimethylsiloxane) chains have been determined from dielectric constant measurements on dilute solutions of the polymer in toluene and carbon tetrachloride at temperatures in the range 10-60Β°C. The temperature coefficient of the dipole moment ratio in toluene wa
