ABSTRACT:
In accordance with the present invention, there is provided a solid organoaluminoxy product prepared by reacting an organoaluminoxane with an oxygen-containing compound selected from the group consisting of organic peroxide, alkylene oxide, or organic carbonate. Further there is provided olefin polymerization catalyst systems comprising the solid organoaluminoxy product and a transition metal-containing catalyst. Still further there is provided processes for the polymerization of olefins using the catalyst systems.
