초록

최근에 소개된 MGQ 모델을 이용하여 poly(ε-caprolactone)(PCL)와 chlorinated polyethylene(CPE) 블렌드의 상용성을 해결하였다. PCL과 상용성을 갖기위한 CPE의 최소한의 이론적인 염소함량은 약 30wt.% 정도였고 이 값는 이미 알려진 실험걸과와 잘 일치하였다. Chlorination정도가 블렌드의 상용성에 미치는 효과는 Binary Interaction(BI) 모델을 이용하여 해석하였다. CPE의 CHCl 단위와 PCL의 CH²COO 단위 사이에는 분자간 상호작용이 존재하며 이러한 상호작용이 블렌드의 상용성에 크게 영향을 미치고 또한 각 고분자를 구성하는 구조단위 사이에 존재하는 상호반발력 역시 상용성 영역의 확대에 기여하는 것으로 해석되었다

The miscibility of poly(ε-caprolactone) (PCL) and chlorinated polyethylenes( CPEs) was studied using the MGQ model. This model predicts that the critical chlorine content in CPEs for the mixture to be miscible is near 30 wt.% . The effect of the degree of chlorination on miscibility is interpreted in terms of the segmental interaction parameters B_ij estimated from the binary interaction(BI) model. It was found that intermolecular interactions between CHCI units in CPE and CH₂COO units PCL are attractive and favorable for mixing of these blends. The intermolecular repulsions between the units in each polymer are also important for miscibility and thus contribute to the broadening of the miscibility boundary.
