Abstract

The present invention relates to supported catalysts for the polymerization of alpha-olefins which comprise the reaction product of: PA1 (a) an Al-alkyl compound; PA1 (b) a silicon compound containing at least one Si--OR or Si--OCOR or Si--NR.sub.2 bond, R being a hydrocarbyl radical; PA1 (c) a solid comprising, as essential support, a Mg dihalide in active form and, supported thereon, a Ti halide or a halo-Ti-alcoholate and a particular type of electron donor compound. The present invention also relates to supported catalyst components.
