ABSTRACT:
Disclose is a water soluble anionic polymer dispersion containing a radical copolymer created in water salt which includes anionic monomer, non-ionic monomer, ionic dispersant and radical polymerization initiator, and anionic surfactant or non-ionic surfactant. Also disclosed is a water soluble anionic polymer dispersion is characterized by containment of radical copolymer created in salt water which includes anionic monomer, non-ionic monomer, ionic dispersant, and radical polymerization initiator, and anionic surfactant, and non-ionic surfactant. Manufacturing methods for the water soluble anionic polymer dispersions are further disclosed herein.
