Abstract:
     Process for preparing a polymer or copolymer from polymerizable monomers by suspension polymerization whereby foam formation during the removal of residual monomers is inhibited, which process comprises adding at least one salt of an inorganic acid having an anionic valency of at least 2 to the polymer slurry prior to the removal of the residual monomer.
