Abstract
Abstract A catalyst component is disclosed for use in the homo- or copolymerization of olefinic hydrocarbons. The catalyst component is comprised of a first compound of the formula Me1(OR1)pR2qX14-p-q and a second compound which is an organocyclic compound having two or more conjugated double bonds. A process is also disclosed for the production of hydrocarbon polymers in which the above catalyst component is combined with a modified or organoaluminum compound to form a catalyst composition capable of providing high molecular weight, wide distribution thereof and other desirable qualities in the polymer product.
