【摘要】 通过PBT/PMMA、PB/PMMA/PC共混物的拉伸行为、动态力学行为和形态,讨论了PC对PBT/PMMA共混体系的性能及形态的影响。指出PC的存在导致共混物中PMMA的粒径变小,使PMMA对PBT显示出增韧效应,但对PBT-PMMA的相容性无明显影响。更多还原

【Abstract】 In the present paper,the tensile behavior,dynamic mechanical properties and morphology of PBT/PMMA blends,as well as PBT/PMMA/PC blends,were studied and the influence of PC on the properties and morphology of the blends were discussed.It was shown that the domain size of PMMA was reduced and PBT was toughened by addition of PC, whereas the compatibility of PBT with PMMA seemed not to be affectet.更多还原
