    摘要： Solid catalyst components for use in olefin polymerization, systems incorporating the same, methods of producing the same, and methods of use are disclosed. The solid catalyst components are formed by (a) dissolving a magnesium compound and an auxiliary intermediate electron donor in at least one first solvent to form a solution; (b) contacting a first titanium compound with said solution to form a precipitate of the magnesium compound and the first titanium compound; (c) washing the precipitate with a mixture of a second titanium compound and at least one second solvent and optionally an electron donor at a temperature of up to 90° C.; and (d) treating the precipitate with a mixture of a third titanium compound and at least one third solvent at 90-150° C. to form a solid catalyst component.

    摘要： The present invention provides a solid organomagnesium precursor having formula {Mg(OR′)X}.a{MgX2}.b{Mg(OR′)2}.c{R′OH}, wherein R′ is selected from a hydrocarbon group, X is selected from a halide group, and a:b:c is in range of 0.01-0.5:0.01-0.5:0.01-5 and process for preparing the same, said process comprising contacting a magnesium source with a solvating agent, an organohalide and an alcohol to obtain the solid organomagnesium precursor. The present invention also provides a process for preparing a catalyst system using the organomagnesium precursor and its use thereof for polymerization of olefins. The organomagnesium precursor is prepared as follows: At 0° C., magnesium in diethyl ether is reacted with the organohalide. After all magnesium has reacted, the calculated amount of alcohol was added and after the completion of addition, the ether was evaporated and a solid compound obtained.
