Abstract

본 발명은 퇴비화가 가능한 지방족 공중합 폴리에스터에 관한 것으로, 좀 더 구체적으로는 하기 일반식(I)과 같은 구조를 갖으며,The present invention relates to a compostable aliphatic copolyester, more specifically, having a structure as shown in general formula (I)

X는 0.1∼80몰%의 페닐렌잔기와 20∼99.9몰%의 지방족 디카르복시산 잔기로 이루어져 있으며, Y는 탄소수가 6이하인 알킬렌글리콜 잔기를 주성분으로 하고, 나머지는 3관능 이상의 말단 히드록시기를 갖는 화합물잔기가 전체 산성분 X에 대해 0.1∼3몰%로 구성된(구성된) 지방족 공중합 폴리에스터에 관한 것으로, 성형 가공특성, 경제성 등이 우수할 뿐만 아니라 퇴비화 과정중에 완전 분해가 가능한 특징이 있다.X is composed of 0.1 to 80 mol% of phenylene residues and 20 to 99.9 mol% of aliphatic dicarboxylic acid residues, Y is mainly composed of alkylene glycol residues having 6 or less carbon atoms, and the rest has a trifunctional or higher functional terminal hydroxyl group. The present invention relates to an aliphatic copolyester composed of 0.1 to 3 mole% of the total acid component X, and has excellent molding process characteristics, economical efficiency, and the like, and can be completely decomposed during composting.
