Abstract

A process for the production of EPRs comprising contacting ethylene, propylene, and, optionally, a diene, under polymerization conditions, with a catalyst system comprising: (A) a catalyst precursor comprising: a vanadium compound; a modifier; and a support, in which the catalyst precursor has been pre-oxidized with an oxidant in an amount sufficient to increase the oxidation state of the vanadium by at least one; (B) a cocatalyst; and (C) optionally, a promoter.
