  • What is anionic polyacrylamide (Apam)?
  • 1. Introduction Anionic polyacrylamide (APAM) is a kind of organic high-molecular polymer with high hydrophilicity and viscosity, which is easily dissolved in water [ , , ].
  • What is polyacrylamide (PAM)?
  • PAM, or anionic Polyacrylamide, is a very long chain, high molecular weight organic polymer produced from natural gas, with characteristics which make it useful as a soil amendment to control runoff and soil loss.
  • What is the molecular weight of Pam?
  • The molecular weight (MW) of commercial PAM ranges from 10 5 to >10 7 Da. High MW PAM (>10 6 Da) has a wider range of applications due to its high viscosity, drag reduction capabilities, and water retention characteristics. 6, 7, 8 PAM is widely used in environmental systems including: 1. 2. 3.
  • 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 ).
