  • Supported catalyst component for ethylene polymerization and copolymerization
    Patent number: 6288005
    Abstract: A catalyst component, adapted for use in the polymerization and copolymerization of ethylene, is formed by reaction of an organomagnesium compound with a metal oxide support to form a supported organomagnesium composition, reaction of the supported organomagnesium composition and a tetraalkyl silicate, contact of the resulting product with a chlorinating reagent, and treatment of the product from the previous step with liquid titanium halide.
    Type: Grant
    Filed: September 28, 1994
    Date of Patent: September 11, 2001
    Assignee: Akzo N.V.
    Inventors: Bor-Ping E. Wang, Elliot I. Band, Ronald A. Epstein
  • Catalyst component for ethylene polymerization
    Patent number: 5244853
    Abstract: Catalyst components for the polymerization of an olefin, such as ethylene, are formed by reacting, in a single reaction step, an organomagnesium compound, an alkoxy silane, and a chlorinating reagent.
    Type: Grant
    Filed: July 27, 1992
    Date of Patent: September 14, 1993
    Assignee: Akzo N.V.
    Inventors: Bor-Ping E. Wang, Elliot I. Band
  • Process of making halide/alkoxy-containing magnesium complex
    Patent number: 5108972
    Abstract: Hydrocarbon-soluble complexes of magnesium haloalkoxides and alcohols (X.sub.n Mg(OR).sub.2-n.mR'OH pR"OH) are prepared in a non-Grignard reaction involving combination of sources of magnesium, halide, and alkoxide in the presence of an excess of the alcohol for the desired alkoxy group and an amount of lower alkyl alcohol to effect the desired solubilization of the complex.
    Type: Grant

    Assignee: Akzo NV
    Inventors: Bor-Ping E. Wang, Elliot I. Band, Andrzej M. Piotrowski, Richard J. Amata
  • Novel halide/alkoxy-containing magnesium compounds
    Patent number: 5081320
    Abstract: Halide alkoxy-containing compounds of the formula ROMgX, where X is halide (e.g., chloride) and R is derived from a C.sub.4 -C.sub.15 normal secondary alcohol (e.g., 2-octanol) are hydrocarbon soluble.
