    摘要: A method of making an olefin polymerization catalyst is disclosed. The method first combines a magnesium halide with an alcohol, then adds a hydroxylated ester and a silicon alkoxide, followed by a titanium compound and another silicon compound to result in a solid composition. This solid composition is then reacted with an aluminum compound and an alkyl halide, followed by reaction with a second titanium compound which may be the same as or different from the first. The second silicon compound is preferably a silicon halide, and the titanium compounds are preferably halides and alkoxides. The aluminum compounds preferably have chloride and alkyl ligands bonded to them.

    摘要: An ethylene-alpha-olefin copolymerization catalyst is prepared by impregnating a silica calcined at elevated temperature sequentially with an organomagnesium compound such as dialkylmagnesium compound, a silane compound which is free of hydroxyl groups, such as tetraethyl orthosilicate. A transition metal component such as titanium tetrachloride is then incorporated into the support. Unexpectedly, the calcination temperature of the silica used to prepare the catalyst precursors has a strong influence on polymer product properties. By increasing the calcination temperature of the silica from 600° to 700° C. or higher temperatures, a catalyst precursor when activated produced ethylene/1-hexene copolymers with narrower molecular weight distributions (MWD) as manifested by a decrease of resin MFR values of ˜3-4 units. Activation of this catalyst precursor with a trialkylaluminum compound results in a catalyst system which is effective for the production of ethylene copolymers.
