US Patent:

52488012, Sep 28, 1993
Filed:

Aug 27, 1992
Appl. No.:

7/935947
Inventors:

Samuel A. Sangokoya - Baton Rouge LA
Assignee:

Ethyl Corporation - Richmond VA
International Classification:

C07F 506
US Classification:

556179
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.

International Classification:

C07F 702
C07F 506
B01J 3100
B01J 3700
US Classification:

502102
Abstract:

Siloxy-aluminoxane compositions which are the reaction products of hydrocarbylsiloxanes substantially-free of Si--OH groups, and aluminoxanes and which have improved solubility and stability in solution even at up to 60 weight percent when compared to the original aluminoxane. The compositions in combination with metallocenes of transition lanithanide and actinide metals form catalysts which can be used in the polymerization of olefins such as ethylene.
