摘　　要：高结晶聚丙烯一般采用高等规度聚丙烯加入成核剂制备。本文较全面地综述了制备高结晶度聚丙烯的催化剂体系及其制备技术。高等规度聚丙烯可以通过传统Ziegler-Natta聚丙烯催化剂与合适的外给电子体搭配制备,也可以通过选取具有合适结构的茂金属化合物制备。目前,聚丙烯工艺主要使用传统Ziegler-Natta催化剂。本文介绍了生产高结晶度聚丙烯的主要生产厂家、牌号和生产工艺,如Spheripol环管/气相工艺、Unipol气相工艺、Novolen气相工艺I、nnovene气相工艺、Hypol釜式本体工艺等,展望了高结晶度聚丙烯的应用前景,认为高结晶聚丙烯是PP新产品开发及高性能化的重要途径之一,具有非常广阔的市场前景,对于我国高结晶度聚丙烯牌号的开发具有较大的意义。High crystallinity Polypropylene （HCPP） typically can be prepared by adding nucleating agentto high isotacticity PP （HIPP）. In this paper, the catalyst systems and catalyst preparation techniques of high crystallinity polypropene （HCPP） were reviewed in details. HIPP can be prepared by via of matching the conventional Ziegler-Natta catalyst with suitable electron donors and choosing suitable metallocene complexes. Presently the conventional Z-N catalysts are mainly used in the PP production process. The manufacturers, grades of HCPP, and the major polymerization processes of HCPP such as Speripol loop/gas-phase polymerization process, Unipol gas-phase polymerization process, Novolen gas-phase polymerization process and Hypol b6lk polymerization processes, etc. were introduced. The application prospects of HCPP were also introduced. Preparation of HCPP is one of the crucial ways to develop new grades PP and high-performance PP, and HCPP has great market potential. Therefore, it will play a significant role in domestic HCPP production.
