  • What is the difference between cationic and anionic polyacrylamide?
  • The molecular weights of cationic polyacrylamide and anionic polyacrylamide are also quite different The molecular weight of cationic polyacrylamide is generally 5 million to 13 million. The molecular weight of anionic polyacrylamide is generally 8 million to 25 million.
  • 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 ).
  • What is the effect of cationic polyacrylamide?
  • The effect of cationic polyacrylamide is several times or tens of times higher than that of anionic, non-ionic polyacrylamide or inorganic salt, because this kind of wastewater generally has negative charge. 2. Application of anionic polyacrylamide (1). Industrial wastewater treatment
