不同端基结构聚丁二酸丁二醇酯的合成和生物降解研究

The Synthesis and Biodegradability Study on Poly( butylene succinate) with Different End-groups

以丁二酸、丁二醇为原料,通过对不同端基的聚丁二酸丁二醇酯(PBS)进行合成和降解,研究了羟基封端、羧基封端和等摩尔比的PBS在堆肥土土壤悬浮液中的降解情况。通过检测降解过程中失重率的变化及降解前后薄膜表面形貌的变化,得出不同端基结构PBS的降解性能。

Poly（butylene succinate） with different end-groups were synthesized by succinic acid （SA） and bu-tanediol （ BD） and were degraded with composting soil suspension.The polymers were observed by weight-loss rati-o and surface morphology.The results showed the degradation of PBS with different end-groups.
