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