Abstract
Vanadium compound/organometallic compound/inorganic oxide catalyst compositions useful for the polymerization of ethylene to polymers having an intermediate molecular weight distribution that can be predictably controlled by the use of a 'tunable' variable are obtained by using, as the vanadium component, a mixture of about 10-90 mol percent of VOCl.sub.3 and, correspondingly, about 90-10 mol percent of VCl.sub.4. The molecular weight distributions of polymers formed in the presence of the catalyst compositions are narrowed as the proportionation of VCl.sub.4 in the vanadium component is increased.
