Abstract

The two liquid state transitions,T ll andT ll, of non-crystalline, uncrosslinked poly(vinyl alcohol) were determined by differential scanning calorimetry.T ll increased as the molecular weightM n increased, whileT′ ll remained almost constant. Crosslinking and crystallinity lead to disappearance of the transitionT ll. The transitionT ll was linked to mobility of whole chains, whereasT′ ll was characteristic of segmental mobility.
