ABSTRACT OF THE DISCLOSURE A process for producing olefin polymers, which comprises polymerizing or copolymerizing olefins in the presence of a catalyst comprising a solid catalyst component and an organoaluminum compound, said solid catalyst component being a titanium compound and/or a vanadium compound supported on a solid product obtained by the reaction between a Grignard compound and a boron compound represented by the general formula B(OR1)aR2bR3c, wherein a, b and c are numbers defined by the formulas 0 < a ? 3, 0 ? b < 3, 0 ? c < 3 and a + b + c = 3, R1 represents a hydrocarbon radical having 1 to 20 carbon atoms, and R2 and R3, which may be the same or different, represent each a hydrogen atom, a hydrocarbon radical having 1 to 20 carbon atoms, or a halogen atom.
