二氧化碳共聚物为基的聚氨酯生物降解性能研究

Study on Biodegradability of Polyurethanes Based on Copolymer of Carbon Diotide

以CO2为起始物合成出聚碳酸亚乙酯（PEC）二醇，进而合成以PEC为预聚物的聚氨酯。对该聚氨酶的力学性能、降解性能等进行了测试。结果表明，该聚氨酯同时具有良好的力学性能和良好的生物降解性能。

This paper has reported the synthesis of Poly(Ethylene Carbonate) Polyurethanes basedon copolymers of CO2.The mechanical properties and biodegradability of this Polyurethanes havebeen tested. The results reveal that this Polyurethanes possess simultaneously good mechanicalproperties and good biodegradability.
