ABSTRACT:
Catalyst components for the polymerization of olefins obtained by reacting a tetravalent titanium halide or halogen alcoholate and an electron-donor compound with a porous polymer support on which is supported a magnesium dihalide or a magnesium compound which does not contain Mg--C bonds and can be transformed into a dihalide, characterized in that the Mg content before and after the reaction with titanium compound ranges from 6 to 12% by weight.
