| 摘 要： | 讨论了CO2 共聚物为基的聚氨酯 -聚碳酸亚乙酯聚氨酯 (PEC-PU)交联方式、交联程度对其生物降解性能的影响。实验结果显示 ,交联程度越大 ,降解程度有所降低 ,但一定交联程度的交联型PEC -PU仍然具有良好的生物降解性能。

| Abstract: | This paper discusses the influences of the way to crosslinking and the crosslink density on the biodegradability of poly(ethylene carbonate)-polyurethanes(PEC-PU).The results show that the rate of biodegradation decreases gradually as the crosslink density increases.The crosslinked PEC-PU in a certain crosslink density still possesses good biodegradability. |
