摘要：

Blends of polychloroprene and epoxidized polyisoprene are demonstrated to be thermodynamically miscible. This miscibility, affirmed by spontaneous interdiffusion between the two polymers, results in the customary single, and composition-dependent, glass transition temperature. Fourier-transform infra-red spectra from the mixture provide direct evidence of specific interaction between the chlorine and the epoxy group. From the invariance of the crystalline melting temperature of the polychloroprene (the equilibrium value of which is determined to be 150-degrees-C), a lower limit of 5 X 10(-2) is estimated for the interaction parameter.
