Olefin polymerization catalyst and method for producing olefin polymer

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 ra.. ... Japan Polypropylene Corporation

Metallocene complex and method for producing olefin polymer

The present invention provides a metallocene complex capable of producing a homopolypropylene having a high melting point in the homopolymerization of propylene, and a production method of an olefin polymer using the same. The metallocene complex of the present invention is represented by formula [i].. ... Japan Polypropylene Corporation

Process for producing ethylene/unsaturated carboxylic acid copolymer, and said copolymer

Provided is a process of effectively producing an ethylene/unsaturated carboxylic acid copolymer having excellent mechanical and thermal properties. A process for producing an ethylene/unsaturated carboxylic acid copolymer comprises: producing an ethylene/unsaturated carboxylic acid ester copolymer from ethylene and unsaturated carboxylic acid ester using a late-transition-metal complex catalyst; and heating the ethylene/unsaturated carboxylic acid ester copolymer at a temperature capable of converting the ester group into a carboxylic acid group, thereby converting into the ethylene/unsaturated carboxylic acid copolymer.. ...
