Zusammenfassung:	Solid catalyst component for the polymerization of olefins, includes the product of the direct reaction, with no subsequent reactions with reducing organometallic compounds, between a titanium compound and a support obtained by contacting a metal oxide containing hydroxyl groups with a solution containing A) a magnesium chloride; B) from 1 to 6 moles of an alcohol per mole of magnesium chloride, in a halogenated hydrocarbon or aromatic hydrocarbon organic solvent C) capable of bringing the magnesium chloride in solution in quantities greater than or equal to 5 grams per liter in the presence of the above-mentioned quantities of alcohol B), the solvent not being able to form adducts with the magnesium chloride.
