Abstract
Compatibilized blends have been prepared to study the effect of compatibilization on the crystallization behavior of the dispersed semicrystalline component. The crystallization behavior of the dispersed phase depended largely on the dispersed domain size and the distribution of the nucleating heterogeneity. Depending on the compatibilization, crystallization of the dispersed phase took place with greater undercooling. As the content of the compatibilizer was increased up to 5 wt% , the dispersed polyamide-6(PA) crystallized coincidently with the matrix high density polyethylene(PE). It was because the homogeneous crystallization of PA occurred at the same temperature of matrix PE crystallization.

상용화 블렌드계에서 상용화 정도가 결정성고분자 분산상의 결정화 거동에 미치는 영향을 조사하였다. 분산상의 결정화 거동은 분산상의 입자 크기와 기핵활성이 있는 heterogeneity의 분산 정도에 크게 의존하였다. 상용화 정도에 따라 분산상의 결정화 온도가 저온 영역으로 크게 이동하였다. 상용화제의 양이 5wt%로 증가했을 때 분산상 polyamide-6(PA)의 결정화가 연속상 고밀도 polyethylene(PE)의 결정화와 같이 일어 났는데 이는 PA의 homogeneous crystallization이 PE의 결정화 온도와 같은 온도에서 진행되기 때문이었다.
