초록
폐폴리염화비닐수지(waste polyvinyl chloride, RPVC)와 폐폴리에틸렌수지(waste polyethylene, RPE)의 블렌드를 용융 혼합으로 제조하였으며 상용화제로서 주쇄는 에틸렌 구조를, 측쇄는 에스터 그룹으로 이루어진 공중합체들을 첨가하여 모폴로지 및 인장특성에 미치는 영향을 조사하였다. RPVC가 연속상인 조성비 85/15 wt%, 중간조성 50/50 wt%, RPE가 연속상인 조성비 15/85 wt%로 RPVC/RPE의 조성비를 변화시켜 이들 조성비에서의 상용화제의 영향을 조사하였다. 모폴로지 관찰로 볼 때RPVC/RPE 블렌드는 10 mm 이상의 도메인 크기를 보여 상용성이 나쁘며 특히 중간조성에서 가장 나쁜 상용성을 나타내었다. 에틸렌 비닐아세테이트 공중합체(EVA)와 에틸렌에틸아크릴레이트 메틸메타크릴레이트 그라프트 공중합체 (ethylene ethylacrylate-graft-methyl methacrylate copolymer, EEA-MMA)가 상용화제로서 우수한 결과를 나타내었다.
The polymer blends of waste polyvinyl chloride (RPVC) and waste polyethylene(RPE) were prepared by melt mixing, and their morphology and tensile properties were evaluated after the copolymers having an ethylene group in backbone and ester group in side position were added as compatibilizers. The blend compositions were varied as follows ; RPVC/RPE 85/15 wt%, where RPVC formed a continuous phase : 50/50, mid composition : 15/85, RPE a continuous phase. The blends revealed a very low compatibility between component polymers because they showed domain sizes greater than 10 mm over all compositions, especially the worst compatibility around mid composition. The blends showed higher compatibility when ethylene vinylacetate copolymer(EVA) and ethylene ethylacrylate-graft-methyl methacrylate copolymers(EEA-MMA) were added.
