  • Does alumina-anionic polyacrylamide adsorption stability depend on Pam chains?
  • The stability mechanism and thermal properties of the system alumina–anionic polyacrylamide (PAM) was stud-ied. The polymers adsorption properties in dependence on the the PAM chains (in the range 530 %) were examined. The turbidimetry method was applied for determination of the sus-pension stability of alumina in the presence of PAM.
  • Do polyacrylamide-type polymers have good thermal stability?
  • Polyacrylamide-type polymers with good thermal stability present good long-term stability at high temperature and high salinity conditions. Viscosity reduction of polyacrylamide-type polymers with good thermal stability was owing to polymer main chain degradation at harsh conditions.
  • Does anionic polyacrylamide increase TSI?
  • the system at pH 6 and 15 °C). Generally, the anionic polyacrylamide addition improves stability of the dispersed solid particles (at fixed pH and temperature, the decrease of TSI values for the system containing PAM in relation to that without polymer is observed).
  • What is anionic polyacrylamide (Apam)?
  • 1. Introduction Anionic polyacrylamide (APAM) is a kind of organic high-molecular polymer with high hydrophilicity and viscosity, which is easily dissolved in water [ , , ].
