Abstract
본 발명은 화학 성질상 감소가 어려운 부반응을 적극적으로 억제하여 섬유용 폴리에스터 고분자의 중합, 가공시 일어날 수 있는 열분해, 색변화등을 방지하므로서 종래보다 우수한 물성을 보유하는 폴리에스터의 제조 방법에 관한 것으로, 이는 하기 일반식(1)로 표기되는 알킬기를 함유한 아민 성분이 전체 폴리에스터에 대해 5~1,000ppm인 것을 특징으로 하는 것이다.The present invention relates to a method for producing a polyester having physical properties superior to those of the prior art by actively inhibiting side reactions that are difficult to reduce due to chemical properties, thereby preventing thermal decomposition and color change that may occur during polymerization, processing of polyester polymer for fibers. This is characterized in that the amine component containing an alkyl group represented by the following general formula (1) is 5 to 1,000 ppm relative to the total polyester.
N(R1, R2, R3) (1)N (R 1 , R 2 , R 3 ) (1)
여기서 R1, R2, R3는 탄소수 2~10의 알킬기.R <1> , R <2> , R <3> is a C2-C10 alkyl group here.
