Organoaluminoxy product, catalyst systems, preparation, and use |
摘要 |
In accordance with the present invention, there is provided an organoaluminoxy product prepared by the process comprising reacting an organoaluminoxane with an ene-ol compound. In another embodiment, the organoaluminoxane can be prepared in situ by the process comprising reacting a hydrocarbylaluminum compound, water, and the ene-ol compound. Further there is provided olefin polymerization catalyst systems comprising the organoaluminoxy product and at least one transition metal-containing catalyst. Optionally, the catalyst system is prepolymerized in the presence of at least one olefin to form a prepolymerized catalyst system. Still further there is provided processes for the polymerization of olefins using the catalyst systems.
