Abstract
Normally sparingly soluble magnesium alkoxide is solubilized in alkanol by the additional presence of certain acidic materials. The resulting solution is used to produce a mixture of substantially spherical particles, substantially free of fines, containing an adduct magnesium alkoxide. The particles are converted by conventional methods to a procatalyst precursor of an olefin polymerization catalyst of good activity and good selectivity to stereoregular polymer whenever appropriate, which catalyst produces polymer product of good morphology.
