摘　　要：选用乙烯-辛烯共聚物接枝马来酸酐(POE-g-MAH)作为反应性增容剂,通过熔融共混技术制备了聚丙烯/聚对苯二甲酸乙二酯(PP/PET)共混合金。扫描电镜(SEM)观察、力学性能及流变性能分析结果表明:POE-g-MAH的添加提高了共混合金的相容性,增强了两相界面的相互作用,促进了分散相粒子的细化。适量的POE-g-MAH可以提高共混合金的力学性能和加工性能。Taking POE-g-MAH as reactive compatibilizer,the PP/PET blends were prepared by melting blending.The properties of the blends were investigated by SEM,mechanical property test,rheological property analysis.The results show that the addition of POE-g-MAH improves the compatibility of the blends,enhances the interaction between the two phases,reduces the particle size of the dispersion phase;the addition of proper amount of POE-g-MAH improves the mechanical and processing properties of the blends.
