Abstract
본발명은 폴리부틸렌 테레프탈레이트계 폴리에스테르를 경질세그먼트로 하고 폴리옥시부틸렌글리콜계 폴리에테르를 연질세그먼트로 하는 폴리에테르에스테르 블록공중합체의 제조방법에 있어서, 술폰산금속염과 3관능성 이상의 알콜을 반응시켜 얻어지는 하기 일반식(I)로 표현되는 화합물을 공중합체에 대해서 0.01~4중량비로 공중합시키는 것을 특징으로 하는 영구변형이 적고 탄성회복율이 우수하며 염색성이 향상된 폴레에테르에스테르 블록공중합체의 제조방법에 관한 것이다.The present invention relates to a method for producing a polyether ester block copolymer having a polybutylene terephthalate polyester as a hard segment and a polyoxybutylene glycol polyether as a soft segment, wherein a sulfonic acid metal salt and a trifunctional or higher alcohol are used. A method for producing a polyether ester block copolymer having low permanent deformation, excellent elastic recovery, and improved dyeability, characterized in that the compound represented by the following general formula (I) obtained by the reaction is copolymerized at 0.01 to 4 weight ratio with respect to the copolymer. It is about.
식중에서, A는 방향족이나 지방족기, B1은 에스테르 형성성 관능기, B2는 B1과 동일하거나, 다른 에스테르 형성성 관능기, M은 금속, m은 1~5의 정수.In the formula, A is an aromatic or aliphatic group, B 1 is an ester-forming functional group, B 2 is the same as B 1 , or another ester-forming functional group, M is a metal, m is an integer of 1 to 5;
