聚氨酯热塑弹性体的热性能及动态力学性能研究
THERMAL AND DYNAMIC MECHANICAL PROPERTIES IN SEGMENTED POLYURETHANES
【摘要】 本文利用热分析及动态力学分析等手段对不同软段结构的聚氨酯热塑弹性体的热性能及动态力学性能进行了研究。实验结果证明链段相容性对形态性能有着决定性的作用。两相结构中的介面层受相容性的影响并对材料的性能有重要的影响
【Abstract】 In the present paper, DSC and DMA were used to study the segment compatiblity-morphology-property relationships in segmented polyurethanes of different soft segments. It is shown that the structure in segmented polyurethanes is strongly dependent on segment compatibility. The interface plays an important role in the thermal and mechanical properties of segmented polyurethanes.
