ABSTRACT:
Olefin polymerization catalysts prepared by reducing transition metal compounds with an organometallic compound are rendered highly efficient by reacting excess organometallic compound with a deactivation agent, such as hydrogen chloride, prior to activation of the catalyst with organoaluminum compounds. Catalyst efficiencies of as high as 700,000 grams of polyethylene per gram of transition metal in the catalyst have been attained at reactor pressures of only 50 psig.
