Document Type and Number:
Japanese Patent JP4823071
Kind Code:
B2
Abstract:
An organometallic transition metal compound is new. An organometallic transition metal compound of formula (I) is new. Independent claims are also included for: (1) a biscyclopentadienyl ligand system of Formula (II); (2) a catalyst system for the polymerization of olefins, comprising the inventive organometallic transition metal compound and co-catalyst which is able to convert the organometallic transition metal compound into a species which is polymerization-active toward olefin; (3) a process for preparing polyolefins by polymerization or copolymerization of olefin in the presence of the catalyst system; (4) use of biscyclopentadienyl ligand system for preparing an organometallic transition metal compound; and (5) a process for preparing organometallic transition metal compound comprising reacting the biscyclopentadienyl ligand system or a bis anion prepared from it with a transition metal compound.
