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.

Supported catalyst component for ethylene polymerization and copolymerization

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.

Catalyst component for ethylene polymerization

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.

Process of making halide/alkoxy-containing magnesium complex

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.

Novel halide/alkoxy-containing magnesium compounds

A catalyst component, adapted for use in the polymerization and copolymerization of ethylene, is formed by reaction of an organomagnesium compound and a tetraaalkyl silicate, contact of the resulting product with a chlorinating reagent, and treatment of the product from the previous step with liquid titanium halide.

Catalyst component for ethylene polyermization and copolymerization

Halide arylalkoxy-containing compounds of the formula ROMgX, where X is halide (e.g., chloride) and R is aralkyl (e.g., benzyl) are hydrocarbon soluble.
