    Abstract: The particle size of popcorn polymers is established during the popcorn polymerization by a process in which reaction mixtures forming popcorn polymers and comprising monoethylenically unsaturated monomers and a crosslinking agent are polymerized in the absence of oxygen and polymerization initiators at up to 200° C. and in which the popcorn polymerization is carried out as a precipitation polymerization in water or in the absence of a solvent and the particle size of the popcorn polymers is controlled in the range from 1 &mgr;m to 10 mm by passing an inert gas stream into the reaction mixture, and popcorn polymers having a mean particle diameter of from >400 &mgr;m to 1500 &mgr;m are used as beverage clarifiers, antidiarrheal drugs and disintegration accelerators for tablets.
