ABSTRACT:
A process and a catalyst for the production of elastomeric primarily isotactic polyolefins characterized by short average blocks lengths wherein olefins are polymerized in the presence of the catalyst which comprises the reaction product of a magnesium alkoxide and a tetravalent titanium halide which takes place in the presence of an electron donor, an organoaluminum compound, and a selectively control agent which is an effectively hindered heterocyclic aromatic nitrogen compound wherein the hindrance is provided by a chloro or a methoxy group.
