【摘要】 本文利用热分析,动态力学分析,应力—应变等手段对共聚醚聚氨酯的相结构及其相应的热性能,力学性能等进行了研究。发现两相结构与硬段含量有着重要关系。两相之间的介面层厚度受链段相容性的影响并对材料的各种物理性能有重要作用。更多还原

【Abstract】 DSC,DMA and stress-strain were used in the present paper to study the thermal and mechanical properties of copolyether-polyurethane thermoplastic elastomer.It was found the multiphase structure was dependent on hard segment content.The interphase layer was strongly dependent on segment compatibility and affect the properties of segmented polyurethanes.更多还原
