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。
The effect of cross-linking degree on the biodegradability of CO2-based polyurethane / poly (ethylene carbonate) polyurethane (PEC-PU) was discussed. The experimental results showed that the larger the degree of crosslinking, the lower the degree of degradation, but a certain degree of cross-linked cross-linked PEC-PU still has good biodegradability.
