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. |
