    摘要: A transition metal-containing catalyst is prepared by(A) reacting in the presence of an inert hydrocarbon diluent(1) the reaction product of(a) an organomagnesium compound;(b) water, carbon dioxide or an organic oxygen-containing compound; and(c) an electron donor or Lewis base;and(2) a transition metal halide;(B) recovering and washing the resultant solid reaction product with an inert hydrocarbon;(C) reacting the washed solid product from (B) with(1) titanium tetrachloride and(2) a reducing agent;(D) stirring the mixture until the brown .beta.-crystalline form of titanium trichloride is transformed into the violet .alpha.-crystalline form; and(E) recovering and washing the resultant solid catalyst with an inert hydrocarbon.
