摘要
以不同相对分子质量的环氧乙烷－四氢呋喃共聚醚、异佛尔酮二异氰酸酯、二苯甲烷二异氰酸酯、１，４－丁二醇、乙二胺等为原料，合成了一系列新型共聚醚型热塑性聚氨酯弹性体，井对其结构和力学性能等进行了研究．
Several copolyether-thermoplastic polyurethanes were prepaed based on different relative molecular mass tetrahydrofuran-ethylene oxide copolyethers, MDI, IPDI,1, 4 - BDO and ED. Their structure and dynamic mechanical properties were also studied.
