  • 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 isoelectric point of amphoteric polymer?
  • The characteristic of amphoteric polymer was also be studied. Throughout the study, we found that the isoelectric point of the amphoteric polyelectrolyte we synthesized is about 7. With the increase in sodium chloride, the reduced viscosity of AmPAM increased.
  • Is ampam a polyampholyte?
  • AmPAM is a typical polyampholyte, carrying both basic groups and acid groups along the same molecular chain (Dobrynin et al. 2004; Song et al. 2006; Hubbe et al. 2007; Silva et al. 2009; Song et al. 2010; Zhu et al. 2015).
