摘要: 通过力学性能、流变性能的测试,以及IR、SEM研究了PES/PA合金在相容剂存在下的微观结构与宏观性能。结果表明,合成的环氧型相容剂与PES/PA合金体系中的PA发生了反应,并且相容剂的加入利于改善PES/PA合金的相容性,流变性和力学性能,尤其是抗冲性能。Abstract: The micro structure and macro properties of PES/PA blend in the presence of compatible agent were studied through the tests of mechanical properties,rheologic properties,IR,DSC and SEM.The results demonstrated that there existed chemical reaction between the compatible agent and PA,so that the presence of the compatible agent can improve the compatibility,rheologic propenties and mechanical properties of PES/PA blend,especially the impact property.
