摘　　要：通过差示扫描量热仪(DSC)、扫描电子显微镜(SEM)对C型氯化聚乙烯(CPE)用高密度聚乙烯(HDPE)YEC-5706的基本物理性能、相对分子质量及其分布、热性能、孔结构和表面形貌、粒径及其分布进行分析。结果表明:YEC-5706能满足C型CPE对原料的要求;SEM照片显示其表面存在大量的丝状连接和孔洞,有利于氯气的扩散并进入颗粒内部。应用试验表明其氯化过程、干燥工序均能满足正常生产要求,其性能均能满足C型CPE的要求。The physical property, relative molecular mass and its distribution, thermal properties, hole structure and surface morphology, particle size and its distribution of high density polyethylene（HDPE） for type C chlorinated polyethylene（CPE） YEC-5706 were analyzed by DSC and SEM. The results show that YEC-5706 can meet the demand of HDPE for type C CPE. SEM photographs show that there exists many filamentous links and holes on the surface which help chlorine spread into the interior of particles. The application experiment indicates that chlorination process and dry procedure can meet the demand of normal industrial production and the properties of type C CPE reach the target.
