ABSTRACT:
A magnesium halide support material for a polyolefin catalysts is disclosed. The magnesium halide of present invention is prepared by reacting magnesium with an alkylhalide in a non-polar hydrocarbon solvent. Preparation of the support does not require the use electron donating solvents and therefore does not require extensive washing to remove the solvent from the support.
