Abstract
The characteristics of nylon6/ionomer semi interpenetrating networks (IPN) as a molded-in-color (MIC) compound had been studied, and comparison was made with nylon6/ionomer blends. Nylon6/ionomer semi IPN shows better homogeneity in phase morphology than nylon6/ionomer blend, and it caused better anti-scratching performance than the blend. This semi IPN structure resulted in lowered crystallization rate, increased melt viscosity and less temperature dependency of viscosity. As a result, we may expect the enhancement of melt processing characteristics in an injection molding process using nylon6/ionomer semi IPN as a MIC compound.

Molded-in-color(MIC) 수지로 사용 가능한 나일론6/이오노머 semi interpenetrating network(IPN)의 물성을 기존 MIC 수지인 나일론6/이오노머 블렌드와 비교하여 살펴보았다. 나일론6/이오노머 semi IPN은 분자 수준의 믹싱인 IPN 구조를 가져 블렌드에 비하여 상대적으로 개선된 homogeneous 형태학적 구조를 가짐에 따라 내스크래칭 특성이 개선됨을 알 수 있었다. 이러한 semi IPN 구조는 나일론6의 결정화 속도를 감소시키며 용융점도의 증가 그리고 점도의 온도 의존성을 감소시켜 블렌드에 비하여 상대적으로 MIC용 사출 가공 특성이 우수해짐을 예측할 수 있었다.
