ABSTRACT:
Soluble methylaluminoxane is prepared by reacting water with a solution of an alkylaluminum compound, wherein at least about half the alkyl groups are methyl groups, in a 1:4 to 4:1 by volume aliphatic hydrocarbon/aromatic hydrocarbon solvent mixture, wherein the aliphatic hydrocarbon solvent has a lower boiling point than the aromatic hydrocarbon solvent, so as to form a product solution of methylaluminoxane in said solvent mixture along with insoluble reaction products which can be removed by filtration. The aliphatic solvent can be removed by vaporization to give a concentrated solution of aluminoxane in the aromatic solvent.
