the present invention is directed to a method for preparing particulate carriers for olefin polymerization procatalysts in which : a heated melt of a complex compound is provided having the formula i mgcl . sub . 2 . nroh . med in which roh is a lower aliphatic alcohol , ed is an electron donor , n is 1 to 6 and m is 0 to 1 , the heated melt is fed to a nozzle atomizing it , the melt to be atomized is sprayed from the nozzle into a chamber , where it is distributed in the form of an atomized melt and then solidified to from fine carrier particles and the fine carrier particles are recovered . during this process an electric charge is fed into the melt to be atomized or which has been atomized , which decreases the surface tension of the solidified melt and prevents the agglomeration of the formed droplets . the charge can be achieved by arranging in connection with the nozzle an electrode , which together with , for example , the grounded melt , forms a static electric couple .
