Solid catalyst components are described which contain Ti, Mg and halogens. These components are reacted with Al metallorganic compounds to provide catalysts which are used for polymerizing .alpha.-olefins. Such a catalyst component is prepared by reacting a Ti compound with the solid halogenation product obtained by reaction of a halogenating agent, different from the halogenated Ti compounds with a, Mg compound selected from the group consisting of: (a) organic oxygenated magnesium compounds containing at least a Mg-O-R linkage wherein R is an alkyl- or cycloalkyl-radical containing up to 20 carbon atoms (b) metallorganic Mg compounds containing at least a Mg-R linkage wherein R is an …
