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 · [ ( mmole MgR / g support ) - 2.1 - 0.55 · wt % ( H 2 O ) / support ] [ mmole MgR / g support ] ( I ) wherein EquAlkanol=molar equivalents of aliphatic or aromatic alkanol relative to the molar amount of magnesium-organic precursor, (mmole MgR/g support)=mmoles of magnesium-organic precursor per gram of particulate solid support, wt % (H2O)/support=weight percent of physically adsorbed water on the solid support, and said magnesium organic precursor compound being converted to a magnesium-oxygen compound.
