The present invention relates to stable aqueous polymer dispersions and a process for their preparation. The aqueous dispersions of the invention have less than about 5 weight percent organic solvent, at least about 30 weight percent solids, a mean particle size of not more than about 400 nm, and a viscosity of less than about 20.0 poise at about ambient temperature.
L'invention concerne des dispersions polymères aqueuses stables ainsi qu'un procédé de leur préparation. Les dispersions aqueuses, selon l'invention, contiennent moins de 5 % en poids environ de solvant organique, au moins 30 % en poids environ de solides, leur dimension particulaire moyenne n'excédant pas 400 nm environ, et leur viscosité est inférieure à environ 20,0 poise à la température ambiante environ.
