摘要
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.
