AbstractAccording to this invention, there is provided a magnesium-containing solid, obtained by contacting the reaction product of (1):a magnesium-containing solid, obtained by contacting the reaction product of:(a) metallic magnesium;(b) a halogenated hydrocarbon of the general formula RX in which R stands for an alkyl, aryl or cycloalkyl group having 1 to 20 carbon atoms, and X stands for a halogen atom; and(c) an alkoxy compound of the general formula X'm C(OR')4-m in which X' stands for a hydrogenor halogen atoms, or an alkyl, aryl or a cycloalkyl group having 1 to 10 carbon atoms, R' stands for an alkyl, aryl or cycloalkyl group having 1 to 20 carbon atoms and m is 0, 1 or 2, with (2) an organic aluminum compound.The magnesium-containing solid is employed as a carrier for a transition metal halide. The supported transition metal halide in combination with an aluminum alkyl cocatalyst such as aluminum triethyl is usefully employed for the polymerization of olefins.
