Abstract

본 발명은 테레프탈릭산에 부탄디올 140~150몰%, 분자량 1400의 폴리테트라메틸글리콜 8~9몰%, 네오펜탈글리콜 20~30몰% 및 이소프탈릭산 15~20몰%를 함께 투입하여 공중합하는 것으로 접착력이 향상된 공중합 폴리에스테르를 제공한다.The present invention is to copolymerize 140 to 150 mol% butanediol, 8 to 9 mol% of polytetramethylglycol having a molecular weight of 1400, 20 to 30 mol% of neopental glycol and 15 to 20 mol% of isophthalic acid to copolymerize terephthalic acid. It provides a copolyester with improved adhesion.
