    摘要: A method for the preparation of supported Ziegler-Natta catalysts comprising contacting a transition metal alkoxide and/or siloxide compound with a magnesium-containing reagent. The magnesium reagent is prepared in the presence of a magnesium chloride support utilizing an anhydrous and oxygen-free mixture of magnesium halide and magnesium metal, slurried in a hydrocarbon solvent. A halogenated hydrocarbon is added to produce the magnesium-containing reagent. Thereafter the transition metal alkoxide and/or siloxide compound is mixed with the slurry. An alkylating agent is added to form an active supported olefin polymerization catalyst.
