ABSTRACT:
A method is disclosed for preparing an olefin polymerization catalyst of improved particle size from a solution of magnesium containing component and a transition metal containing component which is reacted with an organoaluminum halide compound. The improved particle size is provided by employing the organoaluminum halide compound in conjunction with a silicon compound, such as for example an alkyl silicate or a polysiloxane.
