| 摘要 |
<p>The present invention relates to microparticulate materials comprising nanoparticulate cores of inorganic material with oligomeric or polymeric structures containing non-acidic, nucleophilic groups on their surface, where the cores have been agglomerated via an interaction of the non-acidic, nucleophilic groups with at least one further constituent containing electrophilic groups. The present invention furthermore relates to catalysts built up from these materials, to processes for the production of these materials or catalysts, to the use of the catalysts for the polymerisation of olefins, and to a polymerisation process using the catalysts.</p> |
