Abstract

An extension of the mean-field approach for the case of two statistical copolymers is described which allows the analysis of copolymer-copolymer blends of the type AxB1-x + CyB1-y where the copolymer (AxB1-x) with the mole fraction of monomer A (xA) = constant is miscible with the (CyB1-y) copolymer between y = 1 and a single composition limit y = y1, where y1 > 0. Mixtures of poly(a-methyl styrene-co-acrylonitrile) copolymer of azeotrope composition (28.8 wt% acrylonitrile) mixed with statistical methyl methacrylate/acrylonitrile copolymers have been studied and one-phase blends have been found with methyl methacrylate/acrylonitrile copolymers of composition up to 21 wt% acrylonitrile. Estimated segmental interaction parameters acting in the system were positive.
