ABSTRACT:
A high activity alumoxane-metallocene supported catalyst for the polymerization of 1-olefins prepared by reacting undehydrated silica gel with a mixture of trimethylaluminum and triisobutylaluminum to produce a silica-alumoxane product which is then reacted with a Group IVB and/or Group VB metallocene to produce an active catalyst which may be obtained in powder form, suitable for use in gas or slurry phase reactors, by a removal of solvents and drying.
