摘　　要：对采用N型催化剂在不同工业装置上进行丙烯均聚合的试样做物理性能及机械性能分析,讨论了N型催化剂合成聚丙烯的物理性能与其分子构型的关联。结果表明,采用N型催化剂生产的聚丙烯具有较好的立构规整性,这保证了树脂更适于制作纤维制品,也为聚烯烃的物理改性与化学改性提供了适宜的基材。This paper analyzed the physical and mechanical properties of propylene homopolymers synthesized with N catalyst in different commercial plants. The correlation between physical properties and molecular conformation of the propylene homopolymer prepared with high efficiency N catalyst was discussed. The results indicate that the propylene homopolymer produced with N catalyst possesses high stereoregularity; this character ensures the resin to be suitable for manufacturing fiber and make the resin be an appropriate base material for physical and chemical modification of polyolefin.
