Abstract
The miscibility between two kinds of ethylene-vinylalcohol copolymers (EVOH) and three kinds of 4-vinylpyridien-styrene copolymers(PVPST)was studied by differential scanning calorimetry and infrated 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/㎤ 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.

반복단위의 함량이 다양한 에틸렌-비닐알코올 공중합체 (EVOH)와 4-비닐피리딘-스티렌 공중합체(PVPST) 사이의 상용거동을 시차주사열량계 분석, 적외선 분광분석으로 관찰하였다. 상용거동을 binary interaction model로 해석하여 4-비닐피리딘/스티렌, 비닐알코올/스티렌 반복단위 사이의 interaction energy parameter 값이 각각 53.7, 88.1 cal/㎤임을 계산하였다. 이 결과를 이용하여 다양한 EVOH와 PVPST 분자 사이의 상용거동을 예측할 수 있는 miscibility map을 얻었다.
