Abstract

The invention relates to a process for preparing alkylaluminoxanes immobilized on inert support materials from alkylaluminum compounds and water, which is characterized in that the reactants are metered with the gas stream into a fluidized-bed reactor and the reaction product is fixed on the support directly from the gas phase.
