Abstract
Miscibility of blends of bisphenol-A polycarbonate(PC) with various poly(styrene-co-acrylonitrile)(SANs) and poly(α-methylstyrene-co-acrylonitrile) containing 30wt% of acrylonitrile(αSAN30) prepared by solution casting and coprecipitation method was studied by differential scanning calorimetry. PC was found to be partially miscible with those acrylonitrile copolymers. The partial miscibility of blends was varied with AN content, and PC showed better miscibility with αSAN30 than SAN30. The effect of solvents and structure of styrenic component on miscibility was interpreted by a binary interaction model.
시차주사열량계를 이용하여 폴리카보네이트와 몇가지 폴리(스티렌-아크릴로니트릴)공중합체 및 α-메틸스티렌이 함유된 아크릴로니트릴(AN) 공중합체와의 상용성을 조사하였다. 폴리카보네이트는 이들 공중합체와 부분적인 상용성을 보였으며, AN의 함량이 동일한 경우에는 α-메틸스티렌을 함유한 공중합체와의 상용성이 보다 우수하였다. 이러한 결과와 상용성에 미치는 용매효과등을 이성분 상호작용모델로서 고찰하였다.
