Abstract
This invention relates to a process for the production of a catalytic 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 characterized by a process for the production of a catalytic component for the polymerization of olefins, which comprises 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 compound represented by the general formula X.sup.1.sub.n M(OR.sup.1).sub.m-n in which X.sup.1 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, R.sup.1 is a hydrocarbon group of 1 to 20 carbon atoms, m is the atomic valence of M and m>n.gtoreq.0 to obtain a magnesium-containing solid, contacting the magnesium-containing solid with (c) a halogen-containing alcohol and then contacting with (d) a titanium compound and (…
