摘要
对热塑性聚氨酯弹性体的原材料筛选和制备工艺进行了研究,采用一步法可以制备出综合性能较好的热塑性聚氨酯弹性体。用凝胶色谱法(GPC)、傅立叶红外光谱(FTIR)及哈克应力流变仪等方法对制备的热塑性聚氨酯弹性体的分子量、结构和性质进行了表征。
The segmented thermoplastic polyurethane elastomers are prepared successfully by one step process method. The structures and properties of these elastomers are characterized by FTIR analysis, gel permeation chromatography, and ThermoHaake RheoWin tensile test.
