    • According 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'.sub.m C(OR').sub.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.
    • 根据本发明,提供了一种含镁固体,其通过使(1):含镁固体的反应产物与通过使(a)金属镁反应的反应产物接触而获得的含镁固体; (b)通式RX的卤代烃,其中R代表具有1至20个碳原子的烷基,芳基或环烷基,X代表卤素原子; 和(c)通式X'mC(OR')4-m的烷氧基化合物,其中X'代表氢或卤素原子,或具有1-10个碳原子的烷基,芳基或环烷基,R' 代表具有1至20个碳原子且m为0,1或2的烷基,芳基或环烷基,(2)有机铝化合物。 含镁固体用作过渡金属卤化物的载体。 负载的过渡金属卤化物与烷基铝助催化剂如三乙基铝的组合可用于烯烃的聚合。
