Abstract

본 발명은 석신산, 석신산무수화물 또는 석신산에스테르 화합물 중에서 선택된 1종의 화합물을 산성분으로 하고 1, 4-부탄디올을 디올성분으로 하며, 1, 4-사이클로헥산 디메탄올을 산성분에 대하여 1∼30몰%, 3관능 이상의 다관능성 화합물을 산성분에 대하여 0.01∼1몰%의 비율로 첨가하여 220℃ 이하의 온도에서 에스테르화 또는 에스테르 교한반응시켜 반응생성물을 얻고, 이를 ImmHg 이하의 고진공하에서 240℃∼260℃의 온도로 중축합 반응시킴을 특징으로 하는 지방족 공중합 폴리에스터의 제조방법 및 이로 부터 제조된 지방족 공중합 폴리에스터에 관한 것이다.The present invention comprises one compound selected from succinic acid, succinic anhydride, or succinic acid ester compound as an acid component, 1,4-butanediol as a diol component, and 1,4-cyclohexane dimethanol as an acid component. 1 to 30 mol%, trifunctional or more than trifunctional polyfunctional compound is added at a ratio of 0.01 to 1 mol% relative to the acid component and esterified or ester-reacted at a temperature of 220 ° C. or lower to obtain a reaction product, which is high vacuum of ImmHg or less. It relates to a method for producing an aliphatic copolymer polyester characterized in that the polycondensation reaction at a temperature of 240 ℃ to 260 ℃ and an aliphatic copolymer polyester produced therefrom.
