摘　　要：利用偏光显微镜、差示扫描量热仪及扫描电子显微镜等,分析了润滑剂对聚丙烯(PP)表层结晶和形态的影响,结果表明,加入润滑剂可使均聚PP的结晶温度提高、球晶尺寸变小细化,但对共聚PP材料的影响并不大;同时,润滑剂的加入可改善PP制品的耐划伤性能。The impact of lubricant on analyzed by means of polarizing crystallization characteristics light microscope, differential of surface layer of polypropylene （PP） was scanning calorimeter and scanning electron microscope. The results reveal that addition of the lubricant brings about an increase in crystallization temperature and a decrease in spherulite size of homopolymer of propylene, but resulting in little impact on the corresponding properties of copolymer of propylene. Furthermore, the lubricant plays a role in improving the scratch resistance of the PP articles.
