  • 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.
  • How is polyacrylamide (PAM) a polymer with high molecular weight?
  • Polyacrylamide (PAM) with high molecular weight was synthesized by microemulsion method. Polyacrylamide was used as monomer, and a self-made initiator was used for polymerization under the condition of coexistence with sodium carbonate. The optimal polymerization parameters of PAM are determined: pH value of solution was 12. 3.
  • What are the three types of polyacrylamide (PAM)?
  • Polyacrylamide (PAM) and its derivatives are multifunctional water-soluble polymers, which can be divided into three types: nonionic, cationic and anionic. Polyacrylamide (PAM) with high molecular weight was synthesized by microemulsion method.
  • 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.
