  • Is non ionic polyacrylamide a water soluble polymer?
  • Non-ionic polyacrylamide is a water-soluble high molecular polymer or polyelectrolyte. The characteristics of nonionic polyacrylamide PAM can be simply divided into the following three points: It has relatively good water solubility and can be completely dissolved even in cold water.
  • 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?
  • 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 ).
