Abstract: The present disclosure provides a polymerization process for the production of a high melt flow propylene impact copolymer. The process includes contacting an active propylene-based polymer having a melt flow rate greater than about 100 g/10 min with one or more olefins in a polymerization reactor to form the propylene impact copolymer with a melt flow rate greater than about 60 g/10 min. The production of the high melt flow propylene impact copolymer may occur in one or more polymerization reactors, utilizing standard hydrogen concentration, and no visbreaking.
