ABSTRACT CATALYST PRECURSOR PRODUCTION Normally sparingly soluble magnesium alkoxide is solubilized in alkanol by the additional presence of certain acidic materials. The resulting solution is used to prepare a mixture of substantially spherical particles substantially free of fines, containing an adduct magnesium alkoxide. The particles are converted by conventional methods to a precursor of an olefin polymerization catalyst of high activity and high selectivity to stereoregular polymer whenever appropriate.
