Abstract

본 발명은 안티몬을 사용하지 않고 폴리(에틸렌 테레프탈레이트) 단위로부터 폴리에스테르를 제조하는 방법에 관한 것이다. 에스테르화에 이어 리튬 10 내지 75ppm 및 게르마늄 15 내지 80ppm으로 구성되는 혼합 촉매가 축중합 반응에 사용된다. 이렇게 얻은 안티몬이 없는 폴리에스테르는 병류, 시트, 필름, 섬유, 필라멘트 및 성형품의 제조에 사용하기에 적합하다.The present invention relates to a process for producing polyester from poly (ethylene terephthalate) units without the use of antimony. Following esterification, a mixed catalyst consisting of 10 to 75 ppm lithium and 15 to 80 ppm germanium is used in the polycondensation reaction. The antimony free polyesters thus obtained are suitable for use in the manufacture of bottles, sheets, films, fibers, filaments and shaped articles.
