ABSTRACT:
Ethylene-propylene-diene monomer terpolymers having a high degree of random polymerization are produced by employing a high activity, stereo-regular olefin polymerization catalyst comprising a titanium halide-containing procatalyst, an organoaluminum compound cocatalyst and a moderately hindered aromatic heterocyclic amine as selectivity control agent. The terpolymers are elastomeric and exhibit good processability.
