Prepolymerized olefin polymerization catalyst and polymerization process.

摘要

There is provided by the invention a prepolymerized catalyst [I] being obtained by prepolymerizing an alpha -olefin and an polyene compound to [A] a transition metal compound catalyst component and [B] an organometallic compound catalyst component containing a metal selected from metals in Group I to Group III of a periodic table in the total amounts of the alpha -olefin and the polyene compound of 0.01 to 2,000 g per 1 g of the transition metal compound catalyst component [A]. There is also provided by the invention a catalyst for olefin polymerization formed from [I] the prepolymerized catalyst and [II] an organometallic compound catalyst component containing a metal selected from metals in Group I to Group III of a periodic table. The polymerization process of olefin according to the invention is characterized by polymerizing or copolymerizing olefin in the presence of the catalyst for olefin polymerization. The olefin polymer of the invention is an alpha -olefin/polyene copolymer-containing olefin polymer comprising (i) an alpha -olefin/polyene copolymer.
