Abstract
L'invention porte sur une dispersion aqueuse de polymères comprenant (a) un premier polymère cationique hydrosoluble ou gonflant en présence d'eau; et (b) au moins un deuxième polymère hydrosoluble différent du premier; et (c) un sel cosmotrope; et (d) un sel chaotrope. Les quantités de (b), (c) et (d) sont telles qu'il est possible d'obtenir une composition homogène en l'absence de (b). L'invention porte également sur un procédé de formation d'une dispersion aqueuse, sur une méthode d'égouttage d'une suspension de solides dispersés, et sur une méthode de production d'eau clarifiée à l'aide de ladite dispersion.
