Abstract
A process for the polymerization of olefins in the presence of a catalyst comprising a titanium compound and/or vanadium compound supported on a solid carrier and an organoaluminum compound, characterized in that said solid carrier comprises a solid product obtained by the reaction of an organomagnesium compound or a reaction mixture resulting from the organomagnesium compound and at least one compound selected from the group consisting of magnesium hydroxide, calcium hydroxide, zinc hydroxide and aluminum hydroxide, with an aluminum halogenide and/or silicon halogenide, whereby there are produced olefine polymers in an extremely large amount per unit weight of catalyst.
