ABSTRACT:
Polymer powders which are redispersible in an aqueous medium are prepared by drying an aqueous polymer dispersion whose polymer particles dispersed in the aqueous medium have a positive or a negative electric surface charge, with the addition of a water-soluble polyelectrolyte as a drying assistant, the electric charge of the polyion being opposite to the electric surface charge of the disperse polymer particles.
