Summary: | A solid catalyst component for ethylene (co)polymerization, consisting of a particulate silica support and a catalytically active part containing titanium, magnesium, chlorine and alkoxy groups is obtained by a) preparing a solution of magnesium chloride in ethanol; b) impregnating particulate silica with said solution; c) eliminating the unabsorbed ethanol from the suspension; d) eliminating absorbed ethanol from the solid; e) interacting the resultant solid with a titanium chloride, alkoxide or chloroalkoxide; and possibly interacting with an alkylaluminium chloride. In a preferred embodiment in stage e), a silicon halide is added to improve the catalyst activity. |
