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 A_xB_1-x + C_yB_1-y where the copolymer (A_xB_1-x) with the mole fraction of monomer A (x_A) = constant is miscible with the (C_yB_1-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.
