无规共聚聚丙烯研究进展

Research progress of random copolymerized polypropylene

综述了用于生产无规共聚聚丙烯的Ziegler-Natta催化剂和茂金属催化剂的性能及由两种催化剂制备的无规共聚聚丙烯的特点,并总结了近年来关于乙烯-丙烯无规共聚物、丙烯-1-丁烯无规共聚物和其他几种典型的无规共聚聚丙烯产品的聚合机理、聚合工艺及共聚物物理性能的研究进展。

In this paper,the copolymerization performance of Ziegler-Natta catalyst and metallocene catalyst which are used in the production of random copolymerized polypropylene and the characteristics of random copolymerized polypropylene which are produced by the two catalysts are introduced.The research progress on the polymerization mechanism,polymerization process and physical properties of ethylene-propylene random copolymer,propylene-1-butene random copolymer and several other typical random copolymerized polypropylene in recent years is summarized.
