  • Preparation of a magnesium halide support for olefin polymerization and a catalyst composition using the same
    Patent number: 7211534
    Abstract: A magnesium halide support material for a polyolefin catalysts is disclosed. The magnesium halide of present invention is prepared by reacting magnesium with an alkylhalide in a non-polar hydrocarbon solvent. Preparation of the support does not require the use electron donating solvents and therefore does not require extensive washing to remove the solvent from the support.
    Type: Grant

  • Catalyst system for ethylene (co)-polymerization
    Patent number: 6956003
    Abstract: A catalyst system for (co)-polymerizing ethylene or ethylene with ?-olefin is disclosed. The catalyst system utilizes a catalyst component that contains the product of a reaction of an early transition metal complex such as a titanium alkoxide with a cyclic diene-containing compound such as indene. The catalyst system also utilizes a solid magnesium halide support and an alkylaluminum co-catalyst. The catalyst system of present invention produces polyethylene with a narrow molecular weight distribution and a narrow compositional distribution.

  • Catalyst system for ethylene (co)polymerization
    Patent number: 6841498
    Abstract: Disclosed is a new titanium based catalyst system for (co)-polymerizing ethylene or ethylene with alpha-olefin having 3 to 10 carbons. The catalyst is obtained by contacting a magnesium halide support with an aluminum compound and with a titanium halide compound and then treating the resulting solid with a magnesium-amide complex. The catalyst system is suitable for producing ethylene polymer and co-polymer with narrow molecular weight distribution as well as improved branching compositional distribution.
