Catalyst Composition with Phosphorus-Based Donor and Method |
| abstract |
Disclosed are catalyst compositions having an external electron donor which includes one or more of the following compositions: a phosphite, a phosphonite, a pyrophosphite, and/or a diphosphazane. Ziegler-Natta catalyst compositions containing the present external electron donor exhibit strong activity and produce propylene-based olefins with high isotacticity and high melt flow rate. |
