Claims (3)

방향족 폴리에스테르와 지방족 폴리에스테르의 랜덤코폴리머를 제조함에 있어서, 방향족 폴리에스테르 모노머로부터 먼저 중합하여 중합도 80-110으로하고, 계속해서 반응온도를 190-220℃로 내린후 지방족 폴리에스테르를 첨가, 용융하여 촉매 존재하에 에스테르 교환 반응을 일으켜 랜덤 코폴리머를 제조하는 것을 특징으로 하는 코폴리머의 제조방법.In preparing random copolymers of aromatic polyesters and aliphatic polyesters, first polymerization is carried out from an aromatic polyester monomer to a polymerization degree of 80-110, and then the reaction temperature is lowered to 190-220 ° C., and then aliphatic polyester is added and melted. To cause a transesterification reaction in the presence of a catalyst to produce a random copolymer. 제1항에 있어서, 방향족 폴리에스테르와 지방족 폴리에스테르의 혼합중량비가 50:50-90:10인 것을 특징으로 하는 코폴리머의 제조방법.The method for producing a copolymer according to claim 1, wherein the mixed weight ratio of the aromatic polyester and the aliphatic polyester is 50: 50-90: 10. 제1항에 있어서, 방향족 폴리에스테르는 부틸렌 테레프탈레이트, 에틸렌 테레프탈레이트 중에서 에틸렌글리콜과 중합된 것이고, 지방족 폴리에스테르는 폴리카프로락톤임을 특징으로하는 코폴리머의 제조방법.The method of claim 1, wherein the aromatic polyester is polymerized with ethylene glycol in butylene terephthalate and ethylene terephthalate, and the aliphatic polyester is polycaprolactone. ※ 참고사항: 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the original application.
