The phase behaviour of 50/50 blends of a series of terpolymers from styrene, maleic anhydride and acrylonitrile with styrene-acrylonitrile copolymers and styrene-maleic anhydride copolymers has been determined using the single glass transition temperature criterion. The appropriate expression for the overall blend interaction energy density according to the extended Flory Huggins theory is examined and the general shapes of miscibility contours in composition space are deduced and presented in a novel manner. The experimental miscibility is dependent on both terpolymer and copolymer composition, and is well described by this expression using values of segmental interaction parameters available from the literature.
