Abstract

Changes in the glass transition temperature of end-linked networks as a result of the cure process have been studied by examination of a series of stoichiometrically imbalanced PDMS networks covering a wide range of stoichiometric ratio values. The data were compared to existing theories in an effort to resolve the question of cross-link contribution to Tg. The results support the notion based on the Gibbs-DiMarzio theory that elastically effective junctions rather than any branch point dominate the contribution of cross-links to Tg. It has also been shown that existing theories are capable of predicting cure-related changes in Tg for a variety of cross-linked systems.
