The miscibility between two kinds of ethylene-vinylalcohol copolymers (EVOH) and three kinds of 4-vinylpyridine-styrene copolymers (PVPST) was studied by differential scanning calorimetry and infrared spectroscopy. The binary interaction model was used to interpret the observed miscibility behavior, and the calculated interaction energy parameter between 4-vinylpyridine/styrene and vinylalcohol/styrene units were 53.7 and 88.1 cal/cm(3) respectively. These results were used to draw a miscibility map, which can be utilized to anticipate the miscibility between various kinds of EVOH and PVPST.
