摘要：
Disclosed is a process for producing a procatalyst composition having an amide ester internal electron donor. The process includes pre-halogenating a procatalyst precursor before reaction with the amide ester and forming the procatalyst composition. Ziegler-Natta catalyst compositions containing the present procatalyst composition exhibit improved catalyst activity and/or improved catalyst selectivity and produce propylene-based olefins with broad molecular weight distribution.
