摘　　要：介绍了几种Z -N型催化剂体系用液相本体聚合制备的高相对分子质量聚丙烯及利用其制备的双峰聚丙烯 ,讨论了催化剂体系中助催化剂烷基铝用量、不同的给电子体、聚合温度的变化对催化剂活性、聚丙烯相对分子质量的影响。The high molecular weight bimodal polypropylene which was synthesized by means of liquid phase mass polymerization using various NZ system was introduced, as well as bimodal polypropylene. The influences of amount of alkyaluminium, different electron donor and variations of polymerizition temperature on catalyst polymeric activity and polypropylene molecular weight were discussed.
