PROCESS FOR PREPARING POLYMER POLYAHLS

摘要

Process for preparing a polymer polyahl comprising polymerizing an ethylenically unsaturated monomer or mixtures thereof in a ployahl or polyahl mixture whereby a dispersion of polymer particles is prepared in a continuous polyahl phase. The process is characterized by conducting said polymerization in the presence of a halogen, interhalogen or iodine-releasing inorganic compound. The use of the halogen, interhalogen or iodine-releasing inorganic compound provides a more stable polymer polyahl having lower viscosity.
