Abstract
본 발명은 합성섬유용으로 사용되는 폴리에스테르 공중합체의 제조방법에 관한 것으로, 종래의 제조방법에 비해 항필링성, 가공성과 같은 물성의 개량과 함께 제조원가를 낮추도록 한 것이다.The present invention relates to a method for producing a polyester copolymer used for synthetic fibers, and to lower the production cost with the improvement of physical properties such as anti-pilling, processability compared to the conventional manufacturing method.
즉, 본 발명은 테레프탈산과 이소프탈산을 주성분으로 하는 디카르본산과 에틸렌 글리콜 및 하기 일반식(Ⅰ)로 표시되는 2가 알코올을 중축합 반응촉매, 산화 방지제 및 탈색방지제 등의 첨가제의 존재하에 반응시켜 극한점도〔η〕가 0.45∼0.78인 폴리에틸렌 테레프탈레이트-이소프탈레이트-디(또는 트리) 에틸렌글리콜 공중합체를 제조함에 있어 하기 일반식(Ⅰ)로 표시되는 화합물을 에스테르화 반응 초기에 투입해 0.5∼8.0wt% 공중합하는 것을 특징으로 한 것이다.That is, the present invention reacts dicarboxylic acid and ethylene glycol mainly composed of terephthalic acid and isophthalic acid and dihydric alcohols represented by the following general formula (I) in the presence of additives such as polycondensation reaction catalysts, antioxidants and anti-bleaching agents. In preparing a polyethylene terephthalate-isophthalate-di (or tri) ethylene glycol copolymer having an intrinsic viscosity [?] Of 0.45 to 0.78, the compound represented by the following formula (I) It is characterized by copolymerizing -8.0 wt%.
RO-(CH2CH2O)n-H (Ⅰ)RO- (CH 2 CH 2 O) n -H (Ⅰ)
(여기에서, n은 2∼22이며, R은 수소, 메틸, 에틸 또는 페닐기 중에서 선택된 것임)Wherein n is 2 to 22 and R is selected from hydrogen, methyl, ethyl or phenyl group
