Abstract:
1. A method for making a solid catalytic component for a Ziegler-Natta catalyst comprising: a) contacting a porous particulate support with a solution of a hydrocarbon soluble organomagnesium precursor compound in a hydrocarbon solvent; b) reacting said hydrocarbon soluble organomagnesium precursor compound with an amount of aliphatic or aromatic alcohol, said amount being at least about as much as, and not exceeding by more than about 15% of, a molar equivalent of aliphatic or aromatic alcohol Equ wherein Equ (mmole MgR/g support)=mmoles of organgomagnesium precursor compound per gram of particulate solid support wt % (H c) combining a transition metal compound with the porous particulate support and magnesium-oxygen compound to form a reaction mixture.
