  • 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.
  • 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.
  • Why is amphoteric polyacrylamide soluble in water?
  • Amphoteric polyacrylamide has both positive and negative charge groups, which has good water solubility. The anion group can protect the cation group and repel the “impurity anion” in the pulp system, so that the cation group will not be reacted or neutralized too early.
