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). ==References== {{Unreferenced|date=February 2008}} <references/> [[Category:Aluminium compounds]] [[Category:Organometallic compounds]] [[Category:Coordination compounds]] {{inorganic-compound-stub}}
