Abstract

The glass transition temperature (T_g) of poly(phenyl)-, poly(2,6-dimethylphenyl)-, and poly(2,6-diisopropylphenyl)methacrylates, have been measured by DSC. The effect of the nature of the ring substituents on T_g are discussed. Equations for relating glass transition temperatures to average molecular weight (M) are examined. Non-linear dependence between T_g and M^-1 is found, but the relationship between T_g and log M (M = molecular weight) shows a linear dependence. The T_g(∞) values for the polymer studied are determined.
