  • What is amphoteric polyacrylamide (ampam)?
  • Amphoteric polyacrylamide (AmPAM) has been widely used in the wet-end of the papermaking process as a strength additive because of its unique features. AmPAM is a typical polyampholyte, carrying both basic and acid groups along the molecular chain (Dobrynin et al. 2004). Basic and acid groups dissociate in an aqueous solution.
  • What are water soluble polymers based on acrylamide?
  • 1. Introduction Water-soluble polymers based on acrylamide (AM) have shown significant industrial application and are widely used as flocculants, adhesives and viscosity-control agents for enhanced oil recovery, drainage, and retention aids in the paper manufacturer, etc. Citation [1–5]
  • How to determine morphology of ampam dispersion aqueous solution?
  • The morphologies of the particles in AmPAM dispersion were obtained with optical microscope (Olympus BX51, Japan). Rotational viscometer (NXS-11A, China) was used to obtain apparent viscosities of the AmPAM dispersion aqueous solution.
  • 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.
