ABSTRACT OF THE DISCLOSURE In polymerization of an olefin, the use of a novel catalyst has been found to be very effective for providing, with a high catalytic efficiency, a polymer having excellent properties, expecially a high bulk density; said novel catalyst comprising a solid catalyst component and an organometallic compound component; said solid catalyst component being one produced by reacting an organomagnesium component with an H-Si bond-contain- ing chlorosilane compound to form a solid (1); reacting said solid (1) with at least one compound selected from an aldehyde, a silanol, a hydrosiloxane, an alcohol and a thioalcohol, thereby to form a solid (2); and reacting said solid (2) with at least one member selected from a titanium compound, a vanadium compound, a zirconium compound, a hafnium compound, reaction products obtained by a reaction therebetween, and mixtures thereof.
