Beschreibung
Zusammenfassung:	The present invention relates to spherical solid catalyst components for the polymerization of olefins, comprising a titanium compound, supported on a magnesium halide, containing more than one Ti-halogen link and optionally containing groups different from halogen in an amount lower than 0.5 mole per mole of Ti. Spherical solid compounds of the invention are characterized by having a surface area, measured by the BET method, of lower than 70 m /g, a total porosity, measured by the mercurium method, higher than 0.5 cm /g and a pore radius such that at least 50% have values higher than 800 ANGSTROM .
