ABSTRACT:
A process for the preparation of heterogeneous zirconium based catalyst for polymerization of alpha-olefins to super high molecular weight poly (alpha-olefins). The process comprises in mixing zirconium alcholate or phenolate with anhydrous magnesium chloride in the presence of a solvent. The mixture is heated, then cooled and an organoaluminum compound is added. Optionally, an electron donor compound is added and heated to obtain a black slurry, which is cooled and then washed with a hydrocarbon diluent.
