ABSTRACT:
Disclosed are catalysts for the polymerization of alpha-olefins which comprise the reaction product of:
(a) an Al alkyl compound;
(b) a silicon compound containing at least a Si--OR or Si--OCOR or Si--NR.sub.2 bond, R being a hydrocarbyl radical;
(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, selected type of electron-donor compound.
