  • 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.
  • Why is nonionic polyacrylamide used as anti-scouring admixture?
  • Nonionic polyacrylamide was selected as anti-scouring admixture to eliminate the influence of different polymer electrical properties (Lu et al. 2025 ). The molecular weight of PAM is more than 10 million Daltons, and its main chain is connected with a C=O bond and an amino functional group as a branch chain structure, as shown in Fig. 2.
  • What is an anionic polyacrylamide?
  • Anionic polyacrylamides make up the largest portion of the polyacrylamide market. The polymers can be prepared over a wide range of anionic charges and molecular weights (1000 to > 20,000,000 molecular weight). The workhorse comonomer for the production of anionic polyacrylamides is acrylate salts of acrylic acid.
  • 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 ).
