Abstract

본 발명은 폴리에틸렌테레프탈레이트의 제조방법에 관한 것으로, 폴리에틸렌테레프탈레이트 제조시 첨가하는 중축합 촉매 및 열안정제의 투입시점을 조절하므로써 조대입자의 생성을 최소화하여 생산성을 향상시키는 방법에 관한 것이다.The present invention relates to a method for producing polyethylene terephthalate, and to a method for improving productivity by minimizing the generation of coarse particles by controlling the input time of the polycondensation catalyst and the heat stabilizer added during the production of polyethylene terephthalate.
