Prepolymerized olefin polymerization catalyst, olefin polymerization process, and polyolefin obtained thereby.

摘要

There is provided by the invention a prepolymerized catalyst ÄIÜ being obtained by prepolymerizing an a-olefin and an polyene compound to ÄAÜ a transition metal compound catalyst component and ÄBÜ 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 a-olefin and the polyene compound of 0.01 to 2,000 g per 1 g of the transition metal compound catalyst component ÄAÜ. There is also provided by the invention a catalyst for olefin polymerization formed from ÄIÜ the prepolymerized catalyst and ÄIIÜ 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 a-olefin/polyene copolymer-containing olefin polymer comprising (i) an a-olefin/polyene copolymer.
