TRANSITION METAL COMPOUND, OLEFIN POLYMERIZATION CATALYST, AND PROCESS FOR PRODUCING OLEFIN POLYMER BY USING SAID CATALYST

摘要

A novel transition metal compound useful as a compound of an olefin polymerization catalyst, a compound usable as a ligand of the above compound, an efficient process for producing the transition metal compound, and a polymerization catalyst which contains the transition metal compound, has a high activity and an excellent copolymerization performance, and can provide an olefin polymer having a uniform composition and a narrow molecular weight distribution. The transition metal compound is a multi-bridged transition metal complex represented by general formula (I) wherein M represents a group 3-10 or lanthanoid metal element; E<1> and E<2> represent each a sigma - or pi -bonding ligand; X represents a omicron -bonding ligand; Y represents a Lewis base; A<1> ..... A and D represent each a bridging group; n represents 2 to 4; p represents 1 to 4; q represents 1 to 5 and is equal to the valency of M minus 2; r represents 0 to 3; and s represents 0 to 4.
