2 Factors Affecting the Glass Transition in Amorphous Polymers 

Two distinct models have been used for interpreting the influence of features such as chemical stmcture, molecular mass, cross-linking and plasticisers on the glass transition in amorphous polymers. The first approach considers changes in moleeular flexibility, which modify the ease with which conformational changes can take place. The alternative approach relates all these effects to the amount of free volume, which is assumed to attain a critical value at the glass transition.

FACTORS AFFECTING THE GLASS TRANSITION IN AMORPHOUS POLYMERS 195... 

In this chapter we study the characteristics that determine the crystallinity of polymers, crystalline morphology, and the factors affecting the crystallization and melting of polymers. We describe the amorphous state, focusing on the glass transition, a fundamental property for defining the mechanical behavior of polymers. The entire description refers exclusively to synthetic polymers.
