ABSTRACT:
Disclosed are solid catalyst components for the polymerization of olefins comprising a titanium halide or titanium alkoxy halide, and an electron-donor compound selected from silicon compounds of the formula ##STR1## where R.sub.1, R.sub.2, R.sub.3 and R.sub.4 are hydrocarbyl radicals, supported on a magnesium halide in active form.
Also disclosed are catalysts obtained from said catalyst components and from an Al-alkyl compound, as well as catalysts obtained by the reaction of an Al-alkyl compound and a silicon compound of the formula above with a solid catalyst component comprising a titanium halide or halogen alcoholate and an electron-donor compound having specific characteristics of extractability with Al-triethyl, supported on an active magnesium halide.
