Beschreibung
Zusammenfassung:	The present invention relates to stable aqueous polymer dispersions, a process for their preparation, and formulations prepared with the dispersions. The aqueous dispersions of the invention have less than about 2 weight percent organic solvent, at least about 30 weight percent solids, a particle size of not more than about 300 nm, and a viscosity of less than about 20.0 poise at about ambient temperature. La présente invention concerne des dispersions polymères aqueuses stables, leur procédé de préparation, et des formulations préparées à l'aide de ces dispersions. Les dispersions aqueuses de cette invention, qui renferment moins de 2 pour cent en poids environ d'un solvant organique et au moins 30 pour cent en poids environ de solides, présentent une dimension granulométrique ne dépassant pas 300nm et une viscosité inférieure à 20,0 poise environ, à température ambiante.
