Twenty‐five different functionalized and nonfunctionalized polyorganosiloxane microgels were applied as support materials for methylalumoxane (MAO)‐type compounds to give various heterogeneous cocatalysts which are able to activate metallocene complexes like Cp 2 ZrCl 2 for ethene polymerization. The functionalization of the microgels has a strong influence on the properties of the catalysts and the produced polyethenes. © 2001 John Wiley & Sons, Inc. J Appl Polym Sci 80: 281–285, 2001
