PCT No. PCT/JP97/01217 Sec. 371 Date Oct. 7, 1998 Sec. 102(e) Date Oct. 7, 1998 PCT Filed Apr. 9, 1997 PCT Pub. No. WO97/38024 PCT Pub. Date Oct. 16, 1997The 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 comprises a non-crystalline olefin polymer having a specific intrinsic viscosity, glass transition temperature and density, and another known olefin polymer. |
