交联对CO_2共聚物为基聚氨酯降解性能的影响

THE INFLUENCE OF CROSSLINKING ON BIODEGRADABILITY OF POLYURETHANES BASED ON COPOLYMER OF CO_2

讨论ＣＯ２ 共聚物为基聚氨酯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，降解速度有所降低，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。

This paper discusses the influences of the way of 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.
