摘　　要：运用差示扫描量热法和偏光显微镜等分析手段,研究了Mult-920成核剂对高等规聚1-丁烯(i-PB)结晶形态和力学性能的影响。结果表明:Mult-920成核剂最佳添加量是0.15%,该成核剂可以有效减小i-PB球晶粒径及其分布,完善晶型,提高结晶速率和结晶度,同时可以提高i-PB的刚性。It studied the effect of nucleating agent Mult-920 on crystallization and mechanical properties of high isotactic polybutene-1 by differetial scanning caloviactry and polarized light microscope. The results show： the optimum content of nucleating agent Mult-920 is 0.15%, the nucleating agent mult-920 could effectively decrease particle size and particle size distribution, enhance crystal perfection, increase the crystallinity and crystallization rate, and improve the rigidity of i-PB as well.
