  • Process for preparing a diether-based catalyst component
    Patent number: 7033970
    Abstract: A process for preparing a diether-based catalyst component in which: a) a slurry is obtained by contacting a solid support comprising a magnesium halide or a precursor thereof, one or more 1,3-diethers and a liquid phase containing a titanium compound, and b) the obtained slurry is then subjected to a solid/liquid separation step in order to isolate a diether-based catalyst component; said separation step b) being characterized in that the ratio between the solid/liquid separation velocity and the final amount of separated solid must be higher than 0.5 liter/(min·Kg).
