Formation of Ziegler-Natta catalyst using non-blended components

Methods of forming a catalyst, catalysts, polymerization processes and polymers formed therefrom are described herein. The method of forming a catalyst generally includes contacting an alkyl magnesium compound with an alcohol to form a magnesium alkoxide compound; contacting the magnesium alkoxide compound with a first titanium alkoxide and a first agent to form a reaction product "A", wherein the titanium alkoxide and the first agent are nonblended individual components prior to contacting the magnesium alkoxide; and sequentially contacting the reaction product "A" with a second agent, followed by a third agent, and subsequently a first reducing agent to form a catalyst component.
