| titleOfInvention | Polymerization process and catalyst |
| abstract | A process and a catalyst for the production of elastomeric primarily syndiotactic polypropylene characterized by short average block lengths wherein propylene is 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 selectivity control agent which is an effectively hindered heterocyclic aromatic nitrogen compound wherein the hindrance is not provided by a Cl- or methoxy group. |
