摘　　要：采用机械熔融共混的方法,制备了不同添加比例的POM改性PP复合材料,对材料的熔融结晶行为、力学性能及样品的断面形貌进行了表征分析。结果表明,将POM作为改性剂,直接对PP共混改性制得的复合材料具有优异的综合性能。POM含量少于10%时,对PP有增刚和增韧作用,POM/PP复合材料表现出较好的力学性能。POM modified PP composites with different addition ratios were prepared by mechanical melt blending,and their melt crystallization behavior,mechanical properties,and sample cross-sectional morphology were characterized and analyzed.The results showed that the composite materials directly modified by blending PP with POM as a modifier had excellent comprehensive properties,especially when the POM content was less than 10%,it had a stiffening and toughening effect on PP.Meanwhile,POM/PP composite materials exhibited good mechanical properties.
