Abstract

A gas phase method for making elastomeric copolymers of ethylene and higher alpha-olefins comprises contacting a gaseous reaction mixture of the monomers with a fluidized bed of inert support that has been sequentially surface-impregnated with catalyst components comprised of a hydrocarbon-soluble vanadium salt having a vanadium valence of 3 to 5, and an organoaluminium compound, at least one of which catalyst components contains a valence bonded halogen.
