PREDICTING GLASS TRANSITION TEMPERATURES OF PHENYLVINYL ALKYL THIOETHERS AND MALEIC ANHYDRIDE.

The method developed by D. W. Van Krevelen and co-workers for the calculation of glass transition temperature (T//g) from the molar glass transition function was found to be applicable to alternating copolymers. The T//g values of the same copolymers calculated according to the method proposed by A. A. Askadskii and co-workers did not agree with experimental results. By increasing the number of carbon atoms in the alkyl group of copolymers, the disagreement between the calculated and the experimental T//g increases.
