ABSTRACT:
The invention relates to catalysts which produce linear low density polyethylene with a bimodal molecular weight distribution, particularly those containing a high molecular weight fraction. The catalysts are formed by contacting a carrier with an organomagnesium compound to incorporate magnesium into the carrier, and subsequently contacting the carrier containing the incorporated magnesium with a silicon compound and subsequently with a transition metal source; the transition metal containing intermediate is again treated with an organomagesium compound to form a catalyst precursor, and the catalyst precursor is activated with dimethylaluminum chloride.
