A catalyst particularly suitable for use in slurry, particle form, type olefin polymerization is produced by admixing an inorganic oxide with an organic solution of a dihydrocarbyl magnesium compound to form a slurry and then contacting the slurry with a chlorinating agent to convert the dihydrocarbyl magnesium compound to magnesium dichloride, separating the resulting solid support from the liquid, then contacting the separated solid support with a solution of an organic reducing agent, then separating that resulting solid from the liquid, then contacting the recovered solid with a liquid form of a transition metal compound and then separating that resulting solid from the liquid phase. The use of the catalyst in polymerization is also disclosed.
