Abstract:
Disclosed herein are catalyst compositions and polymers, i.e., propylene-based polymers, produced therefrom. The present catalyst compositions include an internal electron donor with a compounded alkoxyalkyl ester and optionally a mixed external electron donor. The present catalyst compositions improve catalyst selectivity, improve catalyst activity, and/or improve hydrogen response. Propylene-based polymer produced from the present catalyst composition has a melt flow rate greater than 10 g/10 min.
