    Abstract: A process may include contacting ethylene monomer with Ziegler-Natta catalyst to form polyethylene. The Ziegler-Natta catalyst may be formed by contacting an alkyl magnesium compound with an alcohol and a metal reagent to form a blend, and contacting the blend with a first agent to form a solution of reaction product “A”. The solution of reaction product “A” may be contacted with a second agent to form a solid reaction product “B”, and the solid reaction product “B” may be contacted with a third agent to form a solid reaction product “C”. The solid reaction product “C” may be contacted with a fourth agent to form a solid reaction product “D”, and the solid reaction product “D” may be contacted with a fifth agent to form a catalyst component.
