ABSTRACT:
The invention relates to a method for the preparation of a supported polymerization catalyst in a multi-function reactor (1) which is equipped with a mixer (2) and at the bottom of which there is fitted a downward substantially conically converging sieve tray (3), possibly detachable, and in which there are carried out, as required for the preparation of the catalyst, an activation stage, i.e. the treatment of the catalyst support with a transition metal compound, washing stages using a suitable solvent, and drying stages using an inert gas, and possibly a prepolymerization of a suitable monomer by means of the obtained activated catalyst and a co-catalyst and possible other compounds, for example a polymerization medium.
