무정형 알파-올레핀 고분자/무정형 폴리아미드 블렌드의 반응 상용화

초록
Maleated 폴리프로필렌과 에틸렌-글리시딜 메타크릴레이트-메틸 아크릴레이트의 공중합체를 반응성 상용화제로 사용하여 무정형 알파-올레핀 고분자/무정형 폴리아미드 블렌드의 반응 상용화를 시도하였다. 무정형 폴리아미드와 상용화제간의 그래프트 반응 정도는 FT-IR, SEM 및 rheometer로 조사하였다. 반응 상용화에 따른 블렌드의 기계적물성 변화 및 하이드로카본 형태의 점착부여수지를 첨가한 블렌드의 접착강도는 만능시험기로 조사하였다.
The reactive compatibilization of amorphous poly-α-olefins (APAO)/amorphous polyamide
(aPA) blends was carried out using two kinds of reactive compatibilizers such as maleated polypropylene and ethylene-glycidyl methacrylate-methyl acrylate copolymer. The grafting reaction rates between aPA and the compatibilizers were examined using FT-IR, SEM and rheometer. The effect of the reactive compatibilization on the mechanical property of the blends was investigated with a universal testing machine. The adhesion strength of the blends including a hydrocarbon tackifier resin, C9 was also measured.
