Procatalyst Composition Including Silyl Ester Internal Donor And Method |
| abstract |
The present disclosure provides silyl esters and silyl diol esters suitable as internal electron donors in procatalysts for polymer production. Disclosed are procatalyst compositions formed from a procatalyst precursor and an internal electron donor that is a silyl ester or a silyl diol ester. The procatalyst compositions can be used with a cocatalyst and optionally an external electron donor and/or an activity limiting agent to form a Ziegler- Natta catalyst composition. The present catalyst compositions exhibit high catalyst activity and form olefin-based polymers with broad molecular weight distribution, favorable flexural modulus, and high isotacticity. |
