Abstract of the Disclosure This invention relates to a supported titanium catalyst component which is prepared by treating a titanium-containing solid with a hydro- carbon, organo halogen compound, e.g., a halogen-substituted hydrocarbon, or mixture thereof, with heating the titanium-containing solid being obtained by subjecting a system consisting of, in combination, a magnesium halide, ordinarily, magnesium dihalide, an organic acid ester and tetra- valent titanium halide to a copulverizing and/or contacting treatment. According to this treatment, the properties and reactivity of the supported titanium catalyst component are completely modified as compared with those before the treatment. In addition, there is described a process for the stereoregular polymerization of .alpha.-olefins wherein homopolymerization or copolymerization of .alpha.-olefins with high polymerization activity and excellent stereoregularity can favourably be accomplished on a commercial scale even in the presence of a molecular weight regulator such as hydrogen by mixing and combining the above-described supported titanium catalyst component with an organo aluminum catalyst component.
