Abstract
Zirconocene dichloride and bis(n-butylcyclopentadienyl)zirconium dichloride are used as catalyst precursors for the heterogeneous polymerization of et hene. A methyl-substituted microgel as support material for heterogeneous c ocatalysts on the basis of MAO is compared with different commercially avai lable silica-supported cocatalysts. The catalyst performances and the prope rties of the obtained polyethenes show considerable differences. (C) 2001 J ohn Wiley & Sons, Inc.
