POLYMERIZATION CATALYST AND PROCESS FOR PRODUCING POLYMERS

摘要

A polymerization catalyst comprising (a) a specific transition metal compound, (b) either a compound capable of reacting with the compound (a) to form an ionic complex or a specific oxygenic compound, and (c) an alkylating agent as an optional ingredient; and a process for producing polymers using the catalyst. By use of this catalyst, polymers reduced in residual metal content and having a high molecular weight are obtained, and simplication of polymer production processes and a reduction in production cost can be attained.
