23443-446 ABSTRACT A process for the preparation of finely divided, spherical magnesium alkoxide is disclosed. The product is prepared by spray drying of an alcoholic solution of the corresponding carboxylated magnesium alkoxide and subsequent drying and decarboxylation of the resulting finely divided carboxylated magnesium alkoxide. The solution is sprayed via a two-material nozzle with inner atomization, which is operated in the part-load range at 10 to 30% of its capacity into an inert accompanying gas which is under a pressure of 1.0 to 1.2 bar, has been preheated to 100-140°C and if fed concurrently. The magnesium alkoxide so prepared is used for the preparation of a catalyst for the polymerization of .alpha.-olefins. Polypropylene prepared using such a catalyst has a high stereospecificity and a high bulk density.
