상용화된 EVOH/SMA 블렌드의 결정화 거동에 관한 연구

Study on the Crystallization Behavior of the Compatible EVOH/SMA Blends

초록

ethylene-vinyl alcohol(EVOH) 공중합체와 styrene-maleic anhydride(SMA) 공중합체를 포함하는 일련의 블렌드계에서 상용화 정도가 결정성 고분자 분산상의 결정화 거동에 미치는 영향을 조사하였다. 블렌드의 결정화거동과 morphology는 각각 시차열량분석기(DSC) 및 주사전자현미경(SEM)을 사용하여 확인하였다. 상용화 정도에 따라 분산상의 결정화 중 일부분이 저온 영역으로 크게 이동하여 나타났다 상용화 블렌드계에서 나타나는 이러한 결정화온도의 이동은 분산상의 homogeneous crystallization에 기인한 것이었다.

A series of blends containing ethylene-vinyl alcohol(EVOH) and styrene-maleic anhydride(SMA) copolymers has been produced to study the effect of compatibilization on the crystallization behavior of the dispersed semicrystalline component. The crystallization behavior and the morphology of the blends have been characterized by differential scanning calorimetry(DSC) and scanning electron microscopy(SEM), respectively. Depending on the compatibilization, a part of crystallization of the dispersed phase took place with greater undercooking. Homogeneous crystallization was responsible for the shift of crystallization temperature for those compatibilized blends.
