Abstract: Process for preparing protective colloid-stabilized polymers of ethylenically unsaturated monomers along with uses for the same. The process includes admixing aqueous dispersions of protective colloid-stabilized polymers of ethylenically unsaturated monomers with one or more drying aids and then drying the mixture. Where one or more salts of organic compounds containing 1 to 10 carbon atoms and optionally one or more protective colloids are used as drying aids. Where 0.1% to 20% by weight based on the dry weight of the aqueous dispersions of the protective colloid-stabilized polymers of salts of organic compounds containing 1 to 10 carbon atoms is used as drying aids.
