Abstract
Aqueous dispersions of cationic water-soluble polymers are provided, as well as processes for making and methods of using the same.
Claims22
A composition comprising an aqueous dispersion comprised of:
- (a) a first cationic water-soluble or water-swellable polymer;
- and
- (b) at least one second water-soluble polymer different from said first polymer;
- and
- (c) a kosmotropic salt;
- and
- (d) a chaotropic salt;
- wherein the amounts of said (b), (c) and (d) are such that a homogeneous composition is obtained in the absence of said (b), and wherein the amounts of said (c) and (d) are effective to reduce the bulk viscosity of said aqueous dispersion.
