High crystallinity Polypropylene (HCPP) typically can be prepared by adding nucleating agent to 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 bulk 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.
