Abstract
A process of forming a Ziegler-Natta catalyst component is disclosed. The process includes contacting an alkyl magnesium compound with an alcohol and a first organoaluminum compound to form a magnesium dialkoxide compound and contacting the magnesium dialkoxide compound with a titanating agent to form reaction product 'A.' The process further includes reacting reaction product 'A' with a halogenating agent to form reaction product “B” and reacting reaction product “B” with a second organoaluminum compound to form a single halogenated catalyst component.
