ABSTRACT:
Aqueous dispersions of anionic water-soluble or water-swellable polymers are provided, where the polymers have an anionic charge of greater than 16% and where the dispersions maintain their form at a pH of 5.1 or greater. Processes for making these dispersions are also disclosed, as well as methods of using these dispersions to treat water containing various types of suspended materials. Dry polymers, preferably formed by drying these aqueous dispersions, are also disclosed.
