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.
