Abstract

본 발명은 새로운 분해성 공중합체에 관한 것으로, 천연 고분자인 리그닌에 매립시 분해가능한 폴리락틱애시드, 폴리글리콜라이드 중에서 선택된 지방족 폴리에스터를 중량비로 리그닌이 25-55%되도록 그라프트시킨 분해서 공중합체를 제공하며, 리그닌에 반응성 기를 도입하기 위하여 하이드로젠 퍼옥사이드, 벤조일 퍼옥사이드, 아세틸 퍼옥사이드, 비스-p-브로모벤조일 퍼옥사이드, 아조비스-이소부틸로니트릴, tert-부틸하이드로퍼옥사이드, 디-tert-부틸 퍼옥사이드, 규멘 하이드로퍼옥사이드(Cumene hydroperoxide) 중에서 선택된 화합물을 처리하여 분해성 폴리에스터와 반응시켜서 제조하며, 이때 지방족 폴리에스터의 분자량은 1만 내지 100만이 바람직하다.The present invention relates to a novel degradable copolymer, wherein the aliphatic polyester selected from degradable polylactic acid and polyglycolide when embedded in lignin, which is a natural polymer, is grafted by lignin in a weight ratio of 25-55%. Hydrogen peroxide, benzoyl peroxide, acetyl peroxide, bis-p-bromobenzoyl peroxide, azobis-isobutylonitrile, tert-butylhydroperoxide, di-tert to introduce reactive groups to lignin. It is prepared by treating a compound selected from -butyl peroxide and cumene hydroperoxide and reacting with degradable polyester, wherein the molecular weight of aliphatic polyester is preferably 10,000 to 1 million.

본 발명에 의한 공중합체는 종래의 리그닌과 비분해성 열가소성 수지의 공중합체에 비하여 분해성이 월등히 우수할 뿐 아니라, 일반 플라스틱과 마찬가지로 용도가 광범위한 잇점을 갖는다.The copolymer according to the present invention is not only excellent in degradability as compared with a copolymer of lignin and a non-degradable thermoplastic resin, but also has a wide range of advantages as in general plastics.
