【摘要】 通过缩聚反应,合成了具有一定软、硬段比例的热塑性聚酯弹性体。应用凝胶渗透色谱、红外光谱以及差示扫描量热法对该热塑性聚酯弹性体结构进行了研究,并测定出其主要的力学性能基本达到进口同类产品D 6356的水平。更多还原

【Abstract】 The thermoplastic polyester elastomer with a certain ratio of soft segment to hard segment was synthesized with polycondensation process. The structure of the elastomer was characterized by gel permeation chromatograph (GPC), infrared spectrometry (IR) and differential scanning calorimetry (DSC). The main mechanical properties of the elastomer were determined.更多还原
