Abstract

Official abstract text for this publication.

Disclosed are procatalyst compositions having an internal electron donor which include a substituted phenylene aromatic diester and optionally an electron donor component. Ziegler-Natta catalyst compositions containing the present procatalyst compositions exhibit high activity and produce propylene-based olefins with broad molecular weight distribution.

First claim

Opening claim text (preview).

The invention claimed is: 1. A procatalyst composition comprising: a combination of a magnesium moiety, a titanium moiety and an internal electron donor comprising a substituted phenylene aromatic diester having the structure (I) wherein R 1 -R 14 are the same or different, each of R 1 -R 14 is selected from the group consisting of hydrogen, a substituted hydrocarbyl…
