Abstract: A new catalyst system, for the homo- and copolymerization of olefins, conjugated or unconjugated dienes or mixtures thereof, is composed of a Ziegler catalyst transition metal compound and an aluminum compound having the general formula:

wherein X is hydrogen or halogen; both R''s are hydrocarbon radicals; and R'' is an unsaturated or saturated aliphatic divalent hydrocarbon radical, unsubstituted cycloalkyl radical or unsubstituted aryl radical.
