摘要：

The non-random-mixing version of the Holey-Huggins theory is used to extract molecular parameters from the experimental equation of state data of polystyrene, poly(p-bromostyrene) and a random copolymer poly(styrene-co-p-bromostyrene) of known composition. With these parameters upper critical miscibility behavior, in qualitative agreement with experimental observations, is predicted for the system poly(styrene-co-p-bromostyrene)/polystyrene. Quantitative agreement can be obtained for the equation of state and miscibility behavior if small changes in the values of the cross parameters are allowed.
