| abstract | The present invention is an alkoxylated bisphenol A represented by the following formula (I), wherein one compound selected from succinic acid, succinic anhydride, or succinic acid ester compound is an acid component, and 1,4-butanediol is a diol component. The reaction product was obtained by adding the compound in an amount of 1 to 30 mol% based on the acid component and at least trifunctional polyfunctional compound at an amount of 0.01 to 1 mol% based on the acid component to esterify or transesterify at a temperature of 220 ° C. or lower. In addition, the present invention relates to a method for producing an aliphatic copolymer polyester characterized in that the polycondensation reaction at a temperature of 240 ~ 260 ℃ under a high vacuum of 1mmHg or less, and an aliphatic copolymer polyester prepared therefrom.n n n n n n n n Where x and y are each an integer from 1 to 10, where x + y ≦ 10,n n n R = H or CH 3 |
