Phase behavior and miscibility in polymer blends containing styrene and 2, 6-dimethyl-1, 4-phenylene oxide derivatives

This article presents a comprehensive and systematc survey of miscibility in binarymixtures of polymers and copolymers based on styrene, on 2, 6-dimethyl-1, 4-phenylene oxide, and on their derivatives. Certain other systems based on methacrylate, acrylonitrile and maleic anhydride-containing polymers are also included to complete the analysis. Experimental and theoretical studies of miscibility and phase behaviors of homopolymer/homopolymer, homopolymer/copolymer and copolymer/copolymer blends are analyzed. A mean-field model is employed to correlate and predict miscibility in new systems. The model is also used to account for the different phenomena governing the miscibility/immiscibility behavior, with special reference to the influence of the chemical structure of the polymers. Tables containing experimental data and related details are included for 127 polymer/polymer systems ; these tables also contain summaries of the binary phase behavior. Calculated segmental interaction parameters, together with the relevant references and recommended values are also tabulated.
