  • Is amphoteric polyacrylamide a water soluble polymer?
  • Amphoteric polyacrylamide (AmPAM) is a linear water-soluble polymer that has been applied in papermaking as an agent for flocculation, retention, filtration, and dry-strength improvement. However, AmPAM with different ranges of molecular weight (MW) have different properties in these processes.
  • What is amphoteric polyacrylamide (ampam)?
  • agents for enhanced oil recovery, drainage, and retention aids in the paper manufacturer, etc.[1–5] Amphoteric polyacrylamide (AmPAM) [6,7] carries anionic and cationic charge group on the polymer back-bone, which can adsorb both organic and inorganic sus-pension substances.
  • What is the retention mechanism of amphoteric polyacrylamide?
  • The retention mechanism of the novel amphoteric polyacrylamide is that the anionic group first neutralizes the cationic waste in the paper material to reduce the electrostatic attraction resistance between the cationic group and the pulp fibers.
  • Does inverse emulsion polymerization affect retention property of amphoteric polyacrylamide?
  • A novel amphoteric polyacrylamide (PDAA) was prepared by inverse emulsion polymerization. The influence of its cationic degree and molecular weight on retention property was discussed.
