PROCATALYST COMPOSITION WITH SUBSTITUTED AMIDE ESTER INTERNAL ELECTRON DONOR
摘要
Disclosed are procatalyst compositions having an internal electron donor which includes a substituted amide ester and optionally an electron donor component. Ziegler-Natta catalyst compositions containing the present procatalyst compositions exhibit improved catalyst activity and/or improved catalyst selectivity and produce propylene-based olefins with broad molecular weight distribution.
