A method for preparing a catalyst precursor material from a dihalo-substituted metalloid is provided. The method comprises mixing in a first reaction zone a first solution of a first component selected from a halogenated alkane, at least one solvent, and a dihalo-substituted Group-14 metalloid or organolithium reagent. continuously adding the first solution to a second reaction zone, and continuously adding a second solution to the second reaction zone. The second solution comprises at least one solvent and a second component of one of a dihalo-substituted Group-14 metalloid or an organolithium reagent, wherein the second component is different from the first component. mixing the first solution and the second solution in the second reaction zone. |
