OLEFIN POLYMERIZATION CATALYST, OLEFIN POLYMERIZATION METHOD, OLEFIN POLYMER COMPOSITIONS, AND THERMOFORMED ARTICLES

摘要

The invention provides catalysts which have a high polymerization activity, enable the obtaining of olefin polymers of wide molecular weight distribution, and which comprise (a)(a-1) a metallocene compound or (a-2) a titanium catalyst component containing magnesium, titanium, and halogen, (b) a compound of a transition metal from Groups 8 to 10 of the periodic table and is of the general formula shown below, and a cocatalyst component. The invention also provides olefin polymer compositions excellent in rigidity and impact resistance which can be produced using a catalyst comprising the transition metal compound (b) and which comprise a non-crystalline olefin polymer having a specific intrinsic viscosity, glass transition temperature and density, and another known olefin polymer. The present invention also provides olefin polymer compositions excellent in mechanical characteristics and heat resistance which can be produced using a catalyst comprising the transition metal compound (b) and which comprise a crystalline olefin polymer having a specific intrinsic viscosity, melting point and density, and another known olefin polymer.
