Claims (1)

에스테르화 또는 에스테르 교환 반응에 이어 중축합 반응을 수행하여 폴리에스테르를 제조하는 방법에 있어서, 에스테르화 또는 에스테르 교환 반응의 반응율이 70% 내지 95%에 다다랐을 때에 반응조내의 진공도를 700 내지 200㎜Hg, 반응온도를 210 내지 250℃로 조절하여 15 내지 60분간 반응시킨 다음 중축합 반응을 수행하는 것을 특징으로 하는 폴리에스테르의 제조방법.In the method for producing a polyester by carrying out the esterification or transesterification reaction followed by a polycondensation reaction, when the reaction rate of the esterification or transesterification reaction reaches 70% to 95%, the vacuum degree in the reaction tank is 700 to 200 mmHg, The reaction temperature is controlled to 210 to 250 ℃ 15 to 60 minutes to react and then a polycondensation method characterized in that to perform a polycondensation reaction. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
