摘　　要：采用熔融共混法制备了茂金属聚乙烯-丁烯-己烯共聚物(mEBHC)/高流动聚丙烯(HF-PP)的共混物,对共混物的结晶行为进行了研究,采用Jeziorny法和Mo法分析了共混物的非等温结晶动力学。结果表明,采用Jeziorny法和Mo法处理非等温结晶过程得到的结果一致,mEBHC的加入,引起了HF-PP成核方式和晶粒生长的变化,提高了共混物的结晶速率。Metallocene poly（ethylene butene-hexene） copolymer （mEBHC） / high-fluidi- ty polypropylene （HF-PP） blends were prepared by melt blending. The crystallization be- havior of the blends was investigated. Jeziorny and Mo models were used to analyse the non-isothermal crystallization kinetics of the blends,respectively. It is found that the re- sult from Jeziorny analysis agrees well with that from Mo analysis. After blending mEBHC, the nucleation and grain growth of HF-PP are changed and the crystallization rate of the blends is improved as well.
