| titleOfInvention | Catalyst formulation and polymerization processes |
| abstract | Processes for the polymerization of olefins with Zeigler-type catalyst systems which involve transition metal catalyst components comprising 4, 5 or 6 transition metals incorporating internal electron donors to provide desired polymerization characteristics, including yield and polymer characteristics. Specific olefins used in the polymerization process are C2-C4 alpha olefins such as propylene in the production of stereoregular polypropylene. The catalyst system comprised a transition metal component having an internal electron donor in an amount providing an internal donor/transition metal mole ratio of no more than 2/3. This is combined with an organoaluminum co-catalyst component to provide a precusor mixture having an aluminum/transition metal mole ration of at least 100. The precusor mixture is combined with an organosilicon external electron donor component in an amount to provide an aluminum/silicon mole ration of no more than 200. The catalyst system is introduced to a polymerization reactor to effect polymerization of the olefin with the catalyst system. |
