Abstract
Dielectric loss measurements using frequencies from 1 to 150 MHz were carried out on four vinyl-type polymers in dilute solutions (PVC, PpCS, PpBS, and PVAc in toluene, dioxane, and carbon tetrachloride) at temperatures from −23° to 60°C. The shape of the absorption curve is always asymmetric, irrespective of the kind of polymer, molecular weight of the polymer, solvent, and temperature. The relaxation time has no molecular-weight dependence. It does, however, depend on the solvent, and is approximately proportional to the solvent viscosity. The activation energy, ΔHA is 3.2—5.9 kcal/mol for each solution, and depends on that of the solvent viscosity, ΔHη, in the manner described by ΔHA=ΔHη+C, where C is a constant. C is proposed to represent the potential energy for the conformational change. It is also proposed that two relaxation mechanisms, a diffusion-controlled mechanism for segmental rotation and a site model, should be taken into consideration simultaneously in order to interpret the dielectric behaviour.
