Abstract: A method for making a solid catalytic component for a Ziegler-Natta catalyst includes contacting a particulate porous support with a solution of a hydrocarbon soluble organomagnesium precursor compound in a hydrocarbon solvent; and reacting said hydrocarbon soluble organo-magnesium precursor compound with an amount of aliphatic or aromatic alcohol, said amount being within an acceptable range of a molar equivalent of aliphatic or aromatic alcohol calculated according to formula (I): Equ Alkanol = 2 ? ยท [ ( mmole ? ? MgR ? / ? g ? ? support ) - 2.1 - 0.
