Received Date: 27 March 1998

Aluminoxanes containing both ethyl and wo-butyl groups were synthesized by the hydrolysis of Al(C₂H₃)₃ (TEA)/A1(i-C₄H₉)₃ (TIBA) mixtures. The aluminoxane made from the TCA/TIBA mixture of molar ratio 7:3 showed cocatalyst activity of about five times as those of ethylaluminoxane or isobutylaluminoxane for ethylene polymerization catalyzed by Cp₂ZrCl₂. The aluminoxane was characterized and the possible reasons for its high activity were discussed.
