Summary This invention relates to a process for the production of a cat- alytic component for the polymerization of olefins, in particular, for the production of a catalytic component capable of exhibiting a high polymerization activity in the polymerization of olefins and giving a polymer containing less low molecular weight components in effective manner. This process is characrerized by a process for the production of a catalytic component for the polymerization of olefins, which com- prises contacting (a) metallic magnesium, (b) a halogenated hydrocarbon represented by the general formula RX wherein R is an alkyl group, ary group or cycloalkyl group having 1 to 20 carbon atoms and (c) a com- pound represented by the general formula X1 n M(OR1) m-n in which X1 is a hydrogen atom, a halogen atom or a hydrocarbon group of 1 to 20 carbon atoms, M is boron, carbon, aluminum, silicon or phosphorus atom, R1 is a hydrocarbon group of 1 to 20 carbon atoms, m is the atomic valence of M and m > n ? 0 to obtain a magnesium-containing solid, contacting the magnesium-containing solid with (c) a halogen-containing alcohol and then containing with (d) a titanium compound and (e) A solid halogen- ated hydrocarbon. - 2 2 -
