PC-1343 ABSTRACT A method of rendering a water soluble anionic polymer more dispersible in water. The method is carried out by mixing in a polar liquid the water soluble anionic polymers and cationic or amphoteric polymers to form a mixture. When the cationic or amphoteric polymer is added to the anionic polymer in an amount of from about 25 to about 75 percent by weight of the anionic polymer, the salt is added to the mixture in order to hydrate the anionic polymers.
