Abstract
본 발명은 접착력이 향상된 공중합 폴리에스테르의 제조방법으로서 테레프탈산 100중량부, 부탄디올 80 내지 100중량부, 에탄디올 30 내지 50중량부, 네오펜탈 글리콜 5 내지 30중량부, 폴리테트라 메틸렌 글리콜 5 내지 13중량부, 이소프탈릭산 10 내지 30중량부 및 1,4-사이크로헥산 디메탄올 5 내지 10중량부가 포함되도록 투입하여 공중합하는 것이며 일반공중합물의 특성을 그대로 갖고 수지상호간의 접착력이 현저히 향상된다.The present invention is a method for producing copolyester with improved adhesion 100 parts by weight of terephthalic acid, 80 to 100 parts by weight of butanediol, 30 to 50 parts by weight of ethanediol, 5 to 30 parts by weight of neopental glycol, 5 to 13 parts by weight of polytetramethylene glycol In addition, it is copolymerized by adding 10 to 30 parts by weight of isophthalic acid and 5 to 10 parts by weight of 1,4-cyclohexane dimethanol, and retains the properties of the general copolymer, and significantly improves adhesion between resins.
