  • What is an anionic polyacrylamide?
  • The anionic polyacrylamides in the oil field industry are designated by the generic name of partially hydrolyzed polyacrylamide (PHPA), although they are in actuality copolymers . Both high- and low-molecular-weight polymers are used as drilling fluid additives.
  • Is polyacrylamide soluble in water?
  • polyacrylamide, an acrylic resin that has the unique property of being soluble in water. It is employed in the treatment of industrial and municipal wastewater. Polyacrylamides are produced by the polymerization of acrylamide (C 3 H 5 NO), a compound obtained by the hydration of acrylonitrile.
  • Which comonomer is used for the production of anionic polyacrylamides?
  • The workhorse comonomer for the production of anionic polyacrylamides is acrylate salts of acrylic acid. These anionic polymers can be prepared as various mono- and divalent metal salts and other positively charged inorganic and organic counterions of the polymerization of acrylic acid with acrylamide (see Fig. 34.4 ).
  • How are water soluble acrylmide-based anionic copolymers prepared?
  • 4. Conclusions Water soluble acrylmide-based anionic copolymers were prepared by free radical solution polymerization. By changing the AMPS monomer feed ratio from 10 to 70 weight percent, while keeping other reaction conditions constant, different anionic copolymers were synthesized.
