摘要：

Miscibility in blends of random copolymers of o-chlorostyrene and p-chlorostyrene [P(oClSy-co-pClS1-y)] with 8 atactic polystyrene (aPS) fractions has been studied at temperatures ranging from 150-degrees-C to 300-degrees-C. Miscibility windows whose size depends on the molecular weight of the PS and on the copolymer composition, y, were observed for each blend. From these data, the temperature dependence of the three segmental interaction parameters required to describe this system were obtained.
