Malpass Dennis Benedict, Piotrowski Andrzej Mieczyslaw: Process for preparation of aluminoxanes.. Texas Alkyls, May 10, 1989: EP0315234-A1 (9 worldwide citation)

Aluminoxanes, useful as olefin polymerization cocatalysts, are formed by admixture of an organoaluminum compound, a water-containing inert, porous absorbent, and an organic solvent. As the absorbent releases the absorbed water, it reacts with the organoaluminum compound thereby forming the aluminoxa ...
