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.

Abstract: The use of redsipersible polymer powders containing no organic emulsifier for a binder in the production of carpeting is surprisingly superior to use of the same polymers in the form of an aqueous dispersion. Tuft removal force in particular, is improved. The compositions contain no thickener, or a reduced level of thickener.
