<p>A method of effectively producing an olefin polymerization catalyst component which exhibits a high activity of polymerizing an olefin to give a polymer having a reduced content of low molecular components, said method comprising bringing into contact with one another (a) metallic magnesium, (b) a halogenated hydrocarbon represented by a general formula RX, wherein R represents C1 to C20 alkyl, aryl or cycloalkyl, and X represents halogen, and (c) a compound of a general formula X1nM(OR1)m-n, wherein X1 represents hydrogen, halogen or C¿1? to C20 hydrocarbyl, M represents boron, carbon, aluminum, silicon or phosphorus, R?1¿ represents C¿1? to C20 hydrocarbyl, m is a valence of M, and m > n » 0, to give a magnesium-containing solid; bringing the solid into contact with a halogenated alcohol; and bringing the product of contact further ìnto contact with a titanium compound and a solid halogenated hydrocarbon.</p> |
