The copolymers prepared in the present work are all soluble in ethyl acetate, THF, DMF and CHCl3 and insoluble in methanol, ethyl ether, and petroleum ether. They are amorphous and show no crystalline DSC endotherm. Results of thermal analysis of VAC-EOCP copolymers are presented in Table . Relatively high Tg of the copolymers (78-154 ºC) in comparison with that of polyvinyl acetate, Tg = 28-31ºC indicates decrease of chain mobility of the copolymer due to the high dipolar character of the EOCP structural units.
