  • Can TGA technique be used on polyacrylamide-type polymer?
  • Concerning the use of TGA technique on polyacrylamide-type polymer, the research work published to date has focused on investigating changes of polymer’s thermal stability as a result of successful modification of polymer structure incorporated with different monomer units , , .
  • Why is anionic polyacrylamide chosen?
  • Anionic polyacrylamide is chosen because the intramolecular electrostatic repulsion between polymer segments forces the polymer chains to adopt a more extended conformation, increasing the efficiency of bridging flocculation.
  • 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.
  • Can thermogravimetric analysis predict long-term stability of polyacrylamide-type polymers?
  • This study aims to apply thermogravimetric analysis technology to develop a facile way for long-term stability prediction of polyacrylamide-type polymers at high temperature and high salinity reservoir conditions, to maintain sufficient viscosity in chemical flooding.
