Abstract
The miscibility behavior observed by enthalpy relaxation method showed that s-PS was miscible with two kinds of a-PS having different molecular weight. In s-PS/a-PS blend, the crystallization of s-PS was increased by the excess amount of added a-PS, whereas the crystallization rate was decreased.

신디오탁틱 폴시스티렌(s-PS)과 두 종류의 분자량이 다른 아탁틱 폴리스티렌(a-PS)과의 상용거동을 enthalpy relaxation 방법으로 조사한 결과, s-PS와 a-PS는 상용성을 가짐을 관찰할 수 있었다. s-PS/a-PS 블렌드에서 첨가된 과량의 a-PS에 의해 s-PS의 결정화도는 증가하였으나, 결정화 속도는 감소하였다.
