Claims (2)

하드세그멘트와 소프트세그멘트로 이루어진 폴리에테르에스테르 블록공중합체에 있어서, 소프트세그멘트를 구성하는 성분으로, 탄소수가 30개 이하인 지방족 디카르복실산이 폴리(알킬렌옥사이드)글리콜에 대해 50 내지 85몰%함유되어 있으면서 고유점도가 0.7 내지 5.0인 것을 특징으로하는 유연성이 우수한 폴리에테르에스테르 블록공중합체.In a polyether ester block copolymer composed of a hard segment and a soft segment, as a component constituting the soft segment, an aliphatic dicarboxylic acid having 30 or less carbon atoms is contained in an amount of 50 to 85 mol% based on the poly (alkylene oxide) glycol. Excellent polyether ester block copolymer, characterized in that the intrinsic viscosity is 0.7 to 5.0. 제1항에 있어서, 탄소수가 30개 이하인 지방족 디카르복실산은 말론산, 숙신산, 클루탈산, 아디프산, 피멜산, 수베르산, 세바스산, 아젤라산, 2-에틸수베르산, 2,2,3,3-테트라메틸숙신산, 디옥틸숙신산, 디메틸아디프산 또는 이들이 저급알킬 에스테르화물이나 무수물 형태의 화합물인 것을 특징으로 하는 유연성이 우수한 폴리에테르에스테르 블록공중합체.The aliphatic dicarboxylic acid of claim 1, wherein the aliphatic dicarboxylic acid has 30 or less carbon atoms includes malonic acid, succinic acid, glutaric acid, adipic acid, pimelic acid, suberic acid, sebacic acid, azelaic acid, 2-ethylsuberic acid, 2, 2,3,3-tetramethylsuccinic acid, dioctylsuccinic acid, dimethyladipic acid, or a polyetherester block copolymer having excellent flexibility, characterized in that they are lower alkyl ester compounds or compounds in the form of anhydrides. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
