'''Aluminoxanes''' refer to compounds that are obtained by the partial hydrolysis of [[trialkylaluminium compound]]s. Aluminoxanes serve as activators for catalytic olefin polymerisation, such as the [[Ziegler-Natta catalyst]]. They also serve a function as [[Scavenger (chemistry)|scavenger]] for impurities (e.g. [[water]]) in reactions that are sensitive to these impurities.
Examples of aluminoxanes include:
* [[Triisobutylaluminoxane]] (TiBAO), formed by the hydrolysis of [[triisobutylaluminium]]
* [[Methylaluminoxane]] (MAO), formed by the hydrolysis of [[trimethylaluminium]]
The [[hydrolysis]] of trialkylaluminium compounds is a highly [[exothermic]] process, and the starting trialkylaluminium compounds are often [[pyrophoric]] (i.e. burns on contact with air).
