EFFECT OF ANNEALING OF POLYMER GLASSES ON THE TEMPERATURE DEPENDENCE OF THE HEAT CAPACITY IN THE SOFTENING RANGE,

Abstract

By the method of dynamic heat capacity the softening of non-crystallizing vitreous polymers, such as polyvinylacetate and polystyrene, was investigated. It was established that the prog ress of heat capacity temperature substantially depended upon (1) heating rate, (2) annealment at temperatures lower than the vitrification temperature, and (3) the rate of the preliminary cooling.
