Реферат: Catalyst components for alpha -olefin polymerization catalysts comprising an organoaluminium compound, an electron donor and a solid catalyst component obtained by reaction of a magnesium-containing compound with a titanium halogen compound, are prepared by the steps of (a) reacting a magnesium alkyl compound with a chlorinating compound; (b) dissolving the chlorinated magnesium alkyl compound in alcohol, optionally after washing; (c) adding to the solution obtained in step (b) magnesium silicate which has been calcined by heating at 200-600 DEG C; (d) adding the mixture obtained in step (c) to a cold medium to precipitate the magnesium compound on the magnesium silicate carrier; (e) separating the resultant solid carrier component. (f) reacting the solid carrier component with a titanium halogen compound in the presence of an internal electron donor. c
