Abstract

Abstract Addition terpolymers of ethylene with an Alpha -olefin and an unsaturated, functionally substituted monomer. Addition tetrapolymers of ethylene with an Alpha -olefin having 3-18 carbon atoms, a nonconjugated diene having only one polymerizable double bond, and an unsaturated, functionally substituted monomer. A process for preparing copolymers of ethylene with an unsaturated functionally substituted monomer, and optionally also with at least one of the following: an Alpha -olefin having 3-18 carbon atoms and a nonconjugated diene having only one polymerizable double bond; wherein the monomers are contacted in the presence of a vanadium compound soluble in hydrocarbons and chlorinated hydrocarbons, in which vanadium is in the oxidation state of at least +3, an organoaluminum compound, and an organic compound having at least one carbon atom substituted by three halogen atoms which can be chlorine or bromine.
