  • What is nonionic polyacrylamide?
  • Nonionic polyacrylamides Nonionic polyacrylamides represent the smallest group of acrylamide-based polymers, representing about 25% of the total polyacrylamide market. Nonionic polyacrylamide is somewhat misleading since in the manufacture of acrylamide, regardless of the route, some degree of hydrolysis of acrylamide occurs.
  • What is an anionic polyacrylamide used for?
  • There is a wide range of uses for anionic polyacrylamides and these include wastewater treatments aids, retention aids, and strength agents in papermaking, hydraulic stimulation, and enhanced oil recovery in oil field applications, mineral processing, and as soil conditioners in agricultural uses.
  • 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 ).
  • Is polyacrylamide contaminated with acrylamide?
  • Polyacrylamide is of low toxicity but its precursor acrylamide is a neurotoxin and carcinogen. Thus, concerns naturally center on the possibility that polyacrylamide is contaminated with acrylamide. Considerable effort is made to scavenge traces of acrylamide from the polymer intended for use near food.
