| 摘 要： | 简要分析了结晶能力、链段柔顺性和化学组成等对聚丁二酸丁二醇酯(PBS)基共聚酯降解性能的影响。结果表明，柔软的链结构易于被生物降解，有规晶态结构阻碍生物降解，脂肪族聚酯比芳香族聚酯易于生物降解，并指出提高PBS基共聚酯的降解性能仍然是一项具有挑战性的工作。

| Abstract: | The effects of crystallinity, chain flexibility, and chemical composition on the degradation behavior of PBS were analyzed in this paper. It was found that the flexible segments promoted, the regular crystalline structure hindered the biodegradability. Aliphatic segments biodegraded easier than the aromatic ones. The degradation remained a challenging problem in the work of improving the performance of PBS-based copolyester. |
