STERICALLY DEMANDING DIALKOKXYDIALKYLSILANES AS EXTERNAL DONORS FOR ZIEGLER CATALYSTS FOR THE POLYMERIZATION OF PROPYLENE |
| 摘要 |
A process for the polymerization of propylene is disclosed. The process may include contacting, in a gas phase polymerization reactor, propylene and optionally one or more comonomers with a catalyst system comprising a Ziegler-Natta catalyst and an external electron donor system comprising di(bicyclo[2.2.1]heptan-2-yl)dimethoxysilane. |

1. A process for polymerizing propylene, the process comprising
contacting, in a gas phase polymerization reactor
propylene, andoptionally one or more comonomers, with a catalyst system comprising
a Ziegler-Natta catalyst, andan external electron donor system comprising di(bicyclo[2.2.1]heptan-2-yl)dimethoxysilane to produce a propylene polymer having a molecular weight distribution in the range from about 4 to less than 5. |
