摘　　要：主要研究成核剂种类及用量对乙烯 -辛烯共聚物 (POE)增韧聚丙烯 (PP)力学性能的影响。研究表明 :随着成核剂NA1的加入 ,PP/POE共混物的透明性、冲击强度、弯曲强度、拉伸屈服强度均明显提高 ,研制的改性PP的透明性、韧性和刚性得到了平衡。Effects of types and content of nucleating agents on mechanical properties of polypropylene/ ethylene octene copolymer(PP/POE) blends were studied.Conclusion showed that with the increase of content of nucleating agent (NA1),transparency,impact strength,flexural strength and tensile yield strength of the blends increased significantly.And the transparency,touhgness and stiffness of the toughened PP were in a good balance.
