Claims (4)

디메틸테레프탈레이트와 에틸렌글리콜을 원료로 하여 폴리에틸렌 테레프탈레이트를 제조함에 있어서, 에스테르교환촉매로 망간아세테이트와 코발트아세테이트를 사용하고, 축중합촉매로서 안티모니트리옥사이드, 디-n-부틸 틴말레이트 또는 이들의 혼합물을 사용하며, 열안정제로서 다음 구조식(I)의 3,5-디-터셔리부틸-4-하이드록시 벤질 포스포닉산의 디에틸 에스테르를 투입하는 것을 특징으로 하는 폴리에스테르의 제조방법.In the production of polyethylene terephthalate using dimethyl terephthalate and ethylene glycol as raw materials, manganese acetate and cobalt acetate are used as the transesterification catalyst, and antimony trioxide, di-n-butyl tin maleate or theirs is used as a condensation polymerization catalyst. A mixture is used, and a method for producing a polyester characterized in that a diethyl ester of 3,5-di-tert-butyl-4-hydroxy benzyl phosphonic acid of the following structural formula (I) is added as a heat stabilizer. 제1항에 있어서, 상기 에스테르 교환촉매는 디메틸테레프탈레이트에 대해 0.1∼10x10-4몰로 첨가는 것을 특징으로 하는 폴리에스테르의 제조방법.The method according to claim 1, wherein the transesterification catalyst is added in an amount of 0.1 to 10x10 -4 moles to dimethyl terephthalate. 제1항에 있어서, 상기 축중합촉매는 디메틸테레프탈레이트에 대해 0.1∼10x10-4몰로 첨가하는 것을 특징으로 하는 폴리에스테르의 제조방법.The method of claim 1, wherein the polycondensation catalyst is added in an amount of 0.1 to 10x10 -4 moles to dimethyl terephthalate. 제1항에 있어서, 상기 열안정제는 중합체에 대해 0.01∼0.5중량%로 첨가하는 것을 특징으로 하는 폴리에스테르의 제조방법.The method of claim 1, wherein the heat stabilizer is added in an amount of 0.01 to 0.5% by weight based on the polymer. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
