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