A method of forming a micronized dry water soluble polymer particles is disclosed herein. In some embodiments, the method includes reducing a particle size of dry water soluble polymer (DWSP) particles; and forming micronized DWSP particles by mixing an additive with the DWSP particles at least one of prior to, during, or after the reduction of the particle size of the DWSP particles, wherein the DWSP is selected from the group consisting of a dry anionic, a dry cationic, a dry nonionic water soluble polymer, and mixtures thereof, wherein the additive is selected from the group consisting of an inorganic oxide, an inorganic hydroxide, an inorganic salt, an organic salt, an insoluble water absorbing material, and mixtures thereof, and wherein a mean particle size of the micronized DWSP particles ranges from about 1 to about 300 microns. |
