  • What is cationic polyacrylamide?
  • Cationic polyacrylamide is a water-soluble polymer that is mainly used for sludge dewatering in municipal wastewater treatment plants. The major physical forms of polyacrylamide include powder, liquid, and emulsion or dispersions. The various end-users of polyacrylamide are water treatment, oil and gas, pulp and paper, mining, and other end-users.
  • 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 ).
  • Why is polyacrylamide production increasing?
  • Polyacrylamide production will be increased by 20,000 metric tons a year to serve mining customers in Asia Pacific SNF plans to increase its global capacity for powder-grade polyacrylamide by 75,000 metric tons (t) each year by the end of 2025, primarily to meet increased demand for the substance in the recovery of oil from old wells.
  • 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.
