Abstract
The miscibility of blends of poly(vinyl chloride), PVC, with transparent acrylonitrile-butadiene-styrene resin, Tr-ABS, which were prepared by solution casting, coprecipitation, and extrusion method, respectively, was examined for glass transition behaviors. While the DSC results of solution-cast blends showed partial miscibility, the blends of PVC/Tr-ABS prepared by coprecipitation and extrusion method were found to be completely miscible at equilibrium. Dynamic mechanical thermal analysis (DMTA) and transmission electron microscopic data of the melt blends revealed that the butadiene rubber particles are dispersed in the glassy polymer matrix as the case of a rubber-toughened plastics. The transmittance observed by UV-visible spectrophotometer for the specimen made of this polymer alloy is considered to be high enough for making transparent goods.

용액주조법, 공침전법, 용융혼합법을 이용하여 염화비닐 수지 (PVC)와 투명 ABS 수지 (Tr-ABS)를 블렌딩시키고 이들 수지의 상용성을 조사하였다. 용액주조법에 의한 블렌드는 두 개의 유리전이온도를 보임으로서 부분적인 상용성을 가진 것으로 나타난 반면, 다른 방법으로 제조된 블렌드는 전 조성에 걸쳐 완전한 상용성을 보여 주었다. 동력학적 (DMTA) 특성 및 투과형 전자 현미경 조사 결과, 용융혼합법으로 제조된 블렌드에는 주로 PVC와 스티렌-아크릴로니트릴(SAN)로 구성된 혼합기질에 부타디엔 고무입자가 분산되어 있는 것으로 밝혀졌으며, 광학분석 결과 이들은 우수한 광 투과성을 보임으로서 고강도 투명성 고분자 합금으로 응용될 수 있을 것으로 보인다.
