Abstract
The miscibility between poly(vinyl chloride) (PVC) and polycaprolactone(PCL)-polyamide block copolymer whose content of PCL block is 62.7wt%, was studied by differential scanning calorimetry. The PCL segment in the block copolymer and PVC has the miscibility showing single glass transition temperature(Tg). The miscible PVC molecule inhibited the crystallizationof PCL segment, making an amorphous homogeneous phase of PCL and PVC segments at high PVC contene. The blends had rubber elasticity at the temperature range between the Tg of amorphous homogeneous phase of PCL and PVC segments and the melting temperature of polyamide segment, when both phases coexist.

Polycaprolactone(PCL) 블록의 함량이 62.7 wt%인 PCL-폴리아미드 블록공중합체와 poly(vinyl chloride) (PVC)의 상용거동을 시차주사열량계로 열적 성질을 관찰하여 조사하고, 블렌드물의 인장물성을 측정하였따. PCL과 PVC 세그먼트는 상용성을 가졌으며, PVC의 함량이 많은 경우 PCL의 결정화가 방해받아 PCL과 PVC 세그먼트로 구성된 비결정성 균일상이 형성됨을 알 수 있었다. PCL/PVC 균일 비결정상과 폴리아미드의 결정상이 변조하는 경우 균일 비결정상의 유리전이온도와 결정상의 논근ㄴ점 사이으이 온도 영역에서 블렌드물은 고무탄성을 가졌다.
