Dielectric transition similar to that found in poly(vinyl acetate) solution was also observed in dioxane solution of poly(vinyl chloride) and poly (p-chlorostyrene) in carbon tetrachloride. It is shown that the dielectric dispersion observed above the transition temperature is attributed to a rotational motion only of a few monomeric units between two bonds undergoing rotation. On the other hand, below the transition temperature, the chain motion is subject to restriction caused by some intrachain interaction and a large number of the monomeric units must move together because of that interaction. Measurements of the intrinsic viscosity on poly(vinyl acetate) in carbon tetrachloride and poly(vinyl chloride) in dioxane show that the transition is a conformational transition from a loosely coiled chain molecule to a compact chain molecule. It is shown that the transition is a kind of globule-coil transition suggested theoretically by some authors.
