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 M¹ (OR¹) p R² q X¹ 4-p-q , a second compound of the formula M² (OR³) m R⁴ n X² z-m-n and a third 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 organoaluminum compound to form a catalyst composition capable of providing controlled molecular weight, wide distribution thereof and other desirable qualities in the polymer product. |
