A catalyst configured to be handled more easily than conventional catalysts and configured to copolymerize an &#x3b1;-olefin and a (meth)acrylic acid ester with high activity. The objects are achieved by polymerization using an olefin polymerization catalyst which contains a metal complex obtained by reacting a ligand having a specific structure and a transition metal compound containing a transition metal selected from nickel or palladium having a specific structure.

Method for producing &#x3b1;-olefin/(meth)acrylic acid ester copolymer

Provided are a novel catalyst component for producing an &#x3b1;-olefin (co)polymer, and a production method using the same. A metal complex is obtainable by contacting a compound represented by the general formula [I] or [II] with a transition metal compound containing a transition metal belonging to 9th to 11th group: wherein R, R, Rand Rrepresent (i) hydrogen, (ii) a halogen, (iii) a linear alkyl or the like, or (iv) ORor the like; Rand Rrepresent a linear alkyl group or the like; any one of R-Rmay have a heteroatom or a heteroatom containing group; Erepresents phosphorus, arsenic or antimony; Xrepresents oxygen or sulfur; Z represents hydrogen or a leaving group.

Metal complex and method for producing the same, catalyst component for olefin polymerization and catalyst for olefin polymerization containing the metal complex, and methods for producing &#x3b1;-olefin polymer and copolymer using the catalyst for olefin polymerization

An object of the present invention is to provide a novel catalyst for olefin (co)polymer production, which has high activity without using a large amount of a cocatalyst and is aimed for obtaining a particulate olefin (co)polymer. The invention relates to an olefin polymerization catalyst which comprises: a solid carrier (1) that has been brought into contact with a specific compound; and a metal catalyst component (2) that contains a transition metal compound (C) containing a transition metal M belonging to Group 9, 10, or 11 of the periodic table and has a reactive group R.
