Catalyst components, methods of forming catalyst compositions, polymerization processes utilizing the catalyst compositions and polymers formed thereby are described herein. The methods generally include providing a magnesium dialkoxide compound, contacting the magnesium dialkoxide compound with a first agent to form a solution of a reaction product "A1", contacting the solution of reaction product "A1" with a reducing agent to form a reduced reaction product "A2", contacting reduced reaction product "A2" with a second agent to form a solid reaction product "A3", contacting solid reaction product "A3" with a metal halide to form reaction product "B" and contacting reaction product "B" with an organoaluminum compound to form a catalyst component.
