Abstract

본 발명은 종래의 플라스틱의 환경오염 문제를 해결할 수 있는 생분해성 고분자 물질을 개발하기 위한 것으로서 지방족 폴리에스테르가 그라프트된 전분 또는 그의 유도체계 공중합체와 그의 제조방법 및 이를 함유한 생분해성 수지조성물을 제공하는 것인바, 더욱 상세하게는 전분 또는 그의 유도체에 지방족 폴리에스테르를 그파프트 공중합시킨 생분해성 및 기계적 물성이 뛰어난 신규의 생분해성 수지와 그의 제조방법 및 이와 같이 제조된 신규한 생분해성 수지를 폴리올레핀과 혼합하여 생분해성의 수지 가공품에 응용된 수지조성물에 관한 것이다.The present invention is to develop a biodegradable polymer material that can solve the environmental pollution problem of conventional plastics, starch or aliphatic copolymer grafted with aliphatic polyester and a method for producing the same and a biodegradable resin composition containing the same More specifically, a new biodegradable resin having excellent biodegradability and mechanical properties obtained by graft copolymerization of an aliphatic polyester to starch or a derivative thereof, a method for preparing the same, and a novel biodegradable resin prepared as described above are polyolefins. The present invention relates to a resin composition which is mixed with and applied to a biodegradable resin processed product.

본 발명에 따른 지방족 폴리에스테르가 그라프트된 전분 또는 그의 유도체계 공중합체는 생분해성, 성형가공성, 기계적 물성이 우수하고 가격이 저렴하여 이를 폴리올레핀과 혼합하여 생분해성 수지조성물을 제조할 수 있다.Starch or aliphatic copolymer grafted with an aliphatic polyester according to the present invention is excellent in biodegradability, moldability, mechanical properties and low cost, so that it can be mixed with polyolefin to produce a biodegradable resin composition.
