CO_2共聚物为基的新型聚氨酯弹性体的合成与性能

Synthesis and properties of new polyurethane elastomers based on copolymer of CO_2

本文报道一类以ＣＯ＿２共聚物为基的新型聚碳酸亚丙酯聚氨酯（ＰＰＣＰＵ）弹性体。探讨了这类弹性体的最佳台成方法．讨论了不同配比，不同的扩链交联剂对弹性体的力学性能的影响。研究了弹性体的热性能及耐水性与不同配比的依赖关系。发现控制适当的配比．能获得耐水住能和耐热性能良好的弹性体。

This paper has reported a New Poly (Proplyene Carbonate ) Polgurethane elas- tomers based on copolymers of CO_2. The most synthesis condition and the casting tech- nology have been studied. The effects of some factors on the mechanical properties of the elastomers were studied.
