CA 2026507

A process for producing a catalyst component for olefin polymerization is provided, which process comprises spraying a solution of a magnesium compound e.g. MgC?2 and an alcohol such as MgC?2nROH (wherein R is 1-10C alkyl and n is 3-6) into a cooled spray column to obtain a spherical solid component (carrier) without any substantial vaporization of the alcohol, followed by partly drying the component for a time till a specified ratio of the alcohol/MgC?2 is attained, and then subjecting the resulting component to treatment with a titanium halide and an electron-donating component, the resulting component having a large particle diameter, without any dispersion of the solvent content in the component particles and also without any breakage of the particles when subjected to treatment with the titanium halides.
