摘要： An ethylene polymerization catalyst is prepared by impregnating a porous support, such as silica, with an organomagnesium compound such as a dialkylmagnesium compound, contacting the magnesium-containing support with a silane compound which is free of hydroxyl groups, such as tetraalkoxysilanes, e.g. tetraethyl orthosilicate, and incorporating a transition metal component, such as titanium tetrachloride, in a specific ratio to the magnesium and silane components. Activation of this catalyst precursor with dimethylaluminum chloride as a cocatalyst results in a catalyst system which is effective for the production of ethylene copolymers with multimodal molecular weight distributions.

摘要： A catalyst composition for copolymerizing ethylene and alpha-olefins is prepared by treating a silica carrier, in a non-polar hydrocarbon solvent, with a dialkyl magnesium compound, a halogen-containing compound and titanium tetrachloride, to form a catalyst precursor and activating the precursor with dimethylaluminum chloride. Also disclosed is a process for copolymerizing ethylene and alpha-olefins in the presence of the catalyst of the invention. The polymer products have multimodal molecular weight distributions unlike unimodal molecular weight distributions of polymers prepared with similar catalyst precursors but activated with different alkylaluminum activators, e.g., triethylaluminum or trimethylaluminum.

摘要： A process is described for forming a catalyst precursor, for copolymerizing ethylene and an alpha-olefin of 3 to 10 carbon atoms, by preparing a contact mixture of an inert solvent, dibutylmagnesium and tetraalkyl orthosilicate which is free of precipitate and adding silica to the contact mixture to form a slurry to form a supported catalyst precursor. Titanium tetrachloride is then incorporated into the support in a specific ratio to the magnesium and silane components. Activation of this catalyst precursor with a trialkylaluminum compound results in a catalyst system which is effective for the production of ethylene copolymers.

摘要： The invention relates to catalysts which produce linear low density polyethylene with a bimodal molecular weight distribution, particularly those containing a high molecular weight fraction. The catalysts are formed by contacting a carrier with an organomagnesium compound to incorporate magnesium into the carrier, and subsequently contacting the carrier containing the incorporated magnesium with a silicon compound and subsequently with a transition metal source; the transition metal containing intermediate is again treated with an organomagesium compound to form a catalyst precursor, and the catalyst precursor is activated with dimethylaluminum chloride.
