Abstract
Novel haloaluminoxane compositions have been formed. The halogen is fluorine, chlorine, and/or bromine, and the amount of halogen atoms present in said composition is in the range of about 0.5 mole % to about 15 mole % relative to aluminum atoms. Processes for producing haloaluminoxane compositions are also provided.
