ABSTRACT:
Propylene polymers of improved melt flow characteristics are obtained in a liquid pool propylene polymerization process carried out in the presence of a magnesium halide supported titanium halide-aluminum trialkyl catalyst system, where prior to its introduction to the polymerization reactor, the magnesium halide supported titanium halide catalyst component is admixed with an aromatic carboxylic acid ester electron donor and the mixture is subsequently introduced into the poymerization zone no later than about 5 days from the time of admixing.
