Abstract

본 발명은 방향족 폴리에스테르를 하드세그먼트로 하고 폴리에테르를 소프트세그먼트로 하여 하드 세그먼트/소프트 세그먼트의 중량분율이 10/90내지 30/70인 폴리에테르에스테 공중합체를 제조항에 있어서, 아래 일반식(I)로 나타나는 스피로환을 갖는 2관능성 화합물을 저분자량 글리콜 성분에 대해 5∼30몰%를 공중합시키므로써 용융점도 및 기타 물성이 우수한 폴리에테르에스테르 공중합체를 제조하는 방법에 관한 것이다.The present invention provides a polyether ester copolymer having an aromatic polyester as a hard segment and a polyether as a soft segment in which the weight fraction of the hard segment / soft segment is 10/90 to 30/70. The present invention relates to a method for producing a polyether ester copolymer having excellent melt viscosity and other physical properties by copolymerizing 5 to 30 mol% of a bifunctional compound having a spiro ring represented by I) with respect to a low molecular weight glycol component.

상기식에서 Rl, R2, R3, R4는 각각 수소, 메틸기, 또는 에틸기이다.In the above formula, R 1 , R 2 , R 3 , and R 4 are each hydrogen, a methyl group, or an ethyl group.
