Abstract
Process for the preparation of solid particles of a magnesium-chloride alcohol adduct comprising (a) forming an emulsion between a MgCl2 .alcohol adduct in molten form and a liquid phase which is immiscible with the said adduct in the presence of a polyalkyl-methacrylate used as a solution having viscosity ranging from 100 to 5000 mm2/s and (b) rapidly cooling the emulsion to solidify the disperse phase and collecting the solid adduct particles.
