ABSTRACT:
A catalyst component for polymerization of olefins, which consists essentially of a particulate contact reaction product of an average particle size of 10 to 100 microns, obtained by contacting the surfaces of particles of a product of contact reaction with a magnesium halide and an alkoxy group-containing compound of a metal of Group I, II, III or IV of the Periodic Table with an alcohol compound and contacting the resulting contact reaction product with a liquid titanium halide. This catalyst component has a high activity and provides a polymer having a relatively large particle size and a narrow particle size distribution.
