  • Does Quaternary polyacrylamide terpolymer resist temperature and salt?
  • So the quaternary copolymer and terpolymer as a whole show good resistance to temperature and salt. Sarsenbekuly et al.15 compared the hydrophobic chain-modified polyacrylamide copolymer RH-4 (see structural Formula 5) with HPAM in the Tahe oil field, Xinjiang, China.
  • Why do Quaternary copolymers and terpolymers have good resistance?
  • The electrostatic repulsion between the groups facilitates the extension of molecular chains, and hydrogen bonding facilitates the enhancement of the bonding strength between molecules and keeps the molecular structure stable. So the quaternary copolymer and terpolymer as a whole show good resistance to temperature and salt.
  • How does acrylamide polymerization work?
  • In comparison to the conventional HPAM gel system, the polymerization of acrylamide and AMPS monomers effectively inhibits the hydrolysis of the amide group, thereby enhancing the polymer’s temperature and salt resistance .
  • Does a high temperature and high salt resistance gel degrade?
  • A gel system with high temperature and high salt resistance has been constructed and assessed. However, this research primarily focused on the stability of the gel in a high-temperature and high salt-environment, and so the gel’s degradability has not been investigated.
