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成核剂最佳的质量分数为0.15%,该成核剂可以有效减小i-PB粒径和球晶粒径分布,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。The effect of nucleating agent on crystallization and mechanical properties of high isotactic polyl-butene by differential scanning calorimetry and polarized light microscope was studied. The results showed that the optimal mass fraction of nucleating agent in the polybutene-1 was about 0.15%. Nucleating agent mult-920 could effectively decrease particle size and particle size distribution , enhanced crystal perfection , crystallinity and crystallization rate. And it was effective to enhance rigidity of polyl-butene.
