以乙二醇和1，4-丁二醇为二元醇，对苯二甲酸二甲酯和己二酸为二元酸，制备了一种可生物降解共聚酯-聚（对苯二甲酸丁二醇-co-己二酸丁二醇-co-对苯二甲酸乙二醇-co-己二酸乙二醇）（PBATE）共聚酯。采用核磁共振、示差扫描量、热重和堆肥实验等手段对共聚酯进行了表征。表征结果显示，所制备的共聚酯不仅具有较好的热性能和力学性能，且具有一定的生物降解性能。

A series of biodegradable aliphatic-aromatic copolyesters,poly(butylene terephthalate-co-butylene adipate-co-ethylene terephthalate-co-ethylene adipate)(PBATE),were synthesized on the basis of ethylene glycol,1,4-butanedioland,adipic acid and dimethyl terephthalate. The obtained PBATE copolyesters were charac-terized by means of 1H NMR,DSC,TG and compost testing. The PBATE copolyester not only possessed better therm odynamic and mechanical properties but also kept good biodegradability.
