ABSTRACT:
Aryloxyaluminoxanes containing the unit ##STR1## where R is unsubstituted or substituted aryl, such as phenyl or naphthyl, are useful as a cocatalysts in Ziegler-Natta and Kaminsky-type olefin polymerization catalysts. They can be formed by reaction of a source of water with an organoaluminum compound containing the desired aryloxy moiety or by reaction of preformed aluminoxane with an organic compound, such as a phenol, containing such a moiety.
