Advance in Research of Catalysts Used in Propylene Polymerization

Advances in research of Ziegler-Natta catalyst,metallocene catalyst and non-metallocene single active site catalyst used in polymerization of propylene were reviewed.Characteristics of the catalysts were discussed.The emphasis focused on donor technology and catalyst preparation process for Ziegler-Natta catalyst,preparation of propylene homopolymer,propylene copolymer and special propylene polymer by metallocene catalyst,and propylene living polymerization,copolymerization of propylene and polar monomer,and aqueous medium polymerization by non-metallocene single active site catalyst.Prospect of the catalysts for propylene polymerization was also briefly discussed.
