Sažetak
This study presents a part of a comprehensive and systematic survey on miscibility in binary blends of homopolymers and copolymers based on styrene, 2, 6-dimethyl-1, 4-phenylene oxide, and their derivatives [1, 2]. Experimental and theoretical studies of miscibility and phase behavior of different polymer blends are analyzed. The FV-UNIQUAC segmental interaction model [3, 4], which is especially suited for correlation and prediction of liquid-liquid equilibrium (LLE) of polymer solutions, is employed to correlate and predict miscibility of polymer blends. Twelve new parameters for binary interactions between different polymer-polymer systems are reported. The parameters were estimated to achieve the best possible representation of the reported experimental equilibrium compositions. The mean absolute deviation between the experimental and the correlated equilibrium compositions of polymer is 2.3 mass %.
