摘　　要：从结晶行为方面分析过氧化物母粒改性前后均聚聚丙烯(PP140)的结晶变化规律。借助差式扫描量热仪(DSC)、偏光显微镜(POM)和X射线衍射分析仪(XRD),研究过氧化物母粒改性前后(过氧化物母粒添加量为0.35%和0.61%)均聚聚丙烯的结晶行为差异,从而为之后分子结构角度研究过氧化物母粒对均聚聚丙烯的改性效果提供基础。This article analyzes the crystallization change of homo-polypropylene(PP140)before and after the peroxide masterbatch modification from the aspect of crystallization behavior.By means of differential scanning calorimeter(D SC),polarizing microscope(POM)and X-ray diffraction analyzer(XRD),the crystallization behavior difference of homo-polypropylene(the amount of peroxide masterbatch added was 0.35%and 0.61%)before and after the modification of the peroxide masterbatch was studied,thus providing a basis for the study of the modification effect of the peroxide masterbatch on homo-polypropylene from the perspective of molecular structure.
