Two reaction methods were employed to prepare alumoxanes of general formula [(RO)AlO]n. The first one from Et3Al, H2O and ROH [R = CH3, (CH3)2CH]; the second one from Et3Al, ROH [R = (CH3)2CH, CH3(CH2)9] and H2O. The properties, chemical composition, aggregation and proposed structure of the final products are discussed based on gel permeation chromatography, molecular weight determination and spectroscopic data.
