摘　　要：对聚丙烯(PP)和聚烯烃弹性体(POE)共混来增韧PP的效果进行研究,通过差示扫描量热计分析了共混物熔点、结晶温度及结晶焓的变化,利用广角X射线衍射仪、透射电镜分别分析了共混物PP晶面间距和共混物中POE的粒径大小和分布。得到PP和POE不同配比共混物性能变化规律。结果也表明,POE增韧PP与POE的添加量粒径大小及分布有密切关系。The effects of PP toughness through blending POE and PP were studied. The changes of blends melting point, crystal temperature and crystal enthalpy were analysed by DSC. Crystallographic interspace of PP, particle size and the distribution of POE in the blends were analysed by WAXD and TEM. Some rules were obtained about PP/POE proporties with different blending ratio. The results show that roughness has the close relation with the content,particle size and the distribution of POE.
