Zirconocene dichloride and bis( n ‐butylcyclopentadienyl)zirconium dichloride are used as catalyst precursors for the heterogeneous polymerization of ethene. A methyl‐substituted microgel as support material for heterogeneous cocatalysts on the basis of MAO is compared with different commercially available silica‐supported cocatalysts. The catalyst performances and the properties of the obtained polyethenes show considerable differences. © 2001 John Wiley & Sons, Inc. J Appl Polym Sci 80: 613–617, 2001
