Claim Text:
1. A process of forming a Ziegler-Natta catalyst comprising: contacting an alkyl magnesium compound with an alcohol and a metal reagent to form a blend of a magnesium dialkoxide compound and a metal; contacting the blend of the magnesium dialkoxide compound and the metal with a first agent to form a solution of reaction product “A”, the first agent comprising a halogenating/titanating agent; contacting the solution of reaction product “A” with a second agent to form a solid reaction product “B”, the second agent comprising a blend of a first metal halide and a metal alkoxide; contacting the solid reaction product “B” with a third agent to form a solid reaction product “C”, the third agent comprising a second metal halide; contacting the solid reaction product “C” with a fourth agent to form a solid reaction product “D”, the fourth agent comprising a third metal halide; and contacting the solid reaction product “D” with a fifth agent to form a catalyst component, the fifth agent comprising an organoaluminum compound; wherein the metal in the metal reagent is selected from Cr
