Abstract
Methylaluminoxane can be formed by the reaction of a tetraalkyldialuminoxane containing C.sub.2 or higher alkyl groups with trimethylaluminum with the trimethylaluminum being present in an amount which is not present in stoichiometric excess. Another embodiment of the present invention involves the synthesis of the methylaluminoxane by reaction of a trialkylaluminum compound or a tetraalkyldialuminoxane containing C.sub.2 or higher alkyl groups with water to form a polyalkylaluminoxane with is then reacted with trimethylaluminum. A third embodiment of the present invention involves the synthesis of the methylaluminoxane by reaction of the aforementioned polyalkylaluminoxane with trimethylaluminum and then with water.
