| abstract |
The present invention relates to a composition based on monofluorometal complexes, a process for the production of monofluorometal complexes, in particular a catalyst system comprising metallocene monofluorides and aluminum alkyls, as well as the use of the catalyst system for the polymerization of unsaturated compounds, in particular for the polymerization and copolymerization of olefins and/or dienes. |
