Abstract
A transition metal catalyst component for polymerization, composed of a metal complex comprising specific ligands and a specific substituted boron group and having a bridging group, which exhibits a very high activity for an olefin type (co)polymerization or an olefin-aromatic vinyl compound copolymerization, whereby the molecular weight of a copolymer obtainable, is high. A method for producing an olefin (co)polymer and an aromatic vinyl compound-olefin copolymer, by means thereof.
