Abstract

A process for the preparation of an olefin polymerization catalyst comprising: gradually adding an organic halide to the magnesium metal in the absence of any complexing diluent to form a magnesium reducing agent; mixing said magnesium reducing agent with an organoaluminum compound to form a cocatalyst; and then mixing said cocatalyst with a titanium tetrahalide, characterized in that the magnesium reducing agent and the organoaluminum compound are ground together before being mixed with said titanium tetrahalide.
