Title: Production of spherical polymers

Abstract: The process for producing bead polymers having a mean particle size of 0.5to 50 .mu.m and a narrow particle size distribution by polymerisation ofmonomers dissolved in a solvent that constitutes a precipitation agent forthe polymers obtained from these monomers is characterized in that thesolvent contains 5 to 3000 ppm of sulfur-free radical interceptors.
