DE ACUERDO CON LA INVENCION SE SUMINISTRA UN PRODUCTO DE ORGANOALUMINOXIDO PREPARADO MEDIANTE UN PROCEDIMIENTO QUE COMPRENDE LA REACCION DE UN ORGANOALUMINOXANO CON UN COMPUESTO DE ENOL. EN OTRA CONFORMACION, EL ORGANOALUMINOXANO PUEDE PREPARARSE IN SITU MEDIANTE EL PROCEDIMIENTO QUE COMPRENDE LA REACCION DE UN COMPUESTO DE HIDROCARBILALUMINIO, AGUA Y EL COMPUESTO DE ENOL. ADEMAS SE SUMINISTRA UN SISTEMA CATALIZADOR PARA LA POLIMERIZACION DE OLEFINAS QUE COMPRENDE EL PRODUCTO DE ORGANOALUMINOXIDO Y AL MENOS UN CATALIZADOR QUE CONTIENE UN METAL DE TRANSICION. OPCIONALMENTE, EL SISTEMA CATALIZADOR SE PREPOLIMERIZA EN LA PRESENCIA DE AL MENOS UNA OLEFINA PARA FORMAR UN SISTEMA CATALIZADOR PREPOLIMERIZADO. ADEMAS, SE SUMINISTRAN PROCEDIMIENTOS PARA LA POLIMERIZACION DE OLEFINAS UTILIZANDO LOS SISTEMAS CATALIZADORES. 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.
