Abstract

본발명은 디메틸테레프탈레이트, 일반식(III)화합물과 에틸렌글리콜을 사용하여 에스테르 교환반응 및 증축합 반응시키되 일반식(III)화합물을 DMT에 대하여 2~90몰% 사용하고 에스테르 교환반응시 2종 이상의 에스테르 교환촉매를, 증축합 반응시 증축합 촉매와 열안정제를 투입하여 반응시킴을 특징으로 하는 용융점이 낮고 유동성과 투명성이 우수하며 일반식(I) 및 (II)가 불규칙하게 존재하는 랜덤공중합 폴리에스테르 및 이의 제조방법에 관한 것이다.The present invention is transesterified and condensation reaction using dimethyl terephthalate, general formula (III) compound and ethylene glycol, 2 ~ 90 mol% of general formula (III) compound to DMT and two kinds The above-mentioned transesterification catalyst is reacted by adding a condensation catalyst and a heat stabilizer during the condensation reaction, and has a low melting point, excellent fluidity and transparency, and random copolymerization of general formulas (I) and (II). It relates to a polyester and a method for producing the same.

여기에서, m+n은 0~8의 정수이고, R 및 R´은 서로 같거나 다른 것으로 각각 할로겐 원자, 수소 원자, 탄소수가 1~8개인 알킬기, 아릴기 또는 아릴알킬기이며, X는 수소원자 또는 할로겐 원자이다.Wherein m + n is an integer of 0 to 8, R and R 'are the same or different and are each a halogen atom, a hydrogen atom, an alkyl group having 1 to 8 carbon atoms, an aryl group or an arylalkyl group, and X is a hydrogen atom Or a halogen atom.
