  • 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.
  • What is thermal stability of water soluble polyacrylamide (PAM) and partially hydrolyzed polymers?
  • Thermal stability of water-soluble polyacrylamide (PAM) and partially hydrolyzed polyacrylamide (HPAM) polymers under various solution conditions have been studied utilizing Quantum Mechanics Density Functional Theory (DFT) computational modeling method.
  • How rheological studies are performed with partially hydrolyzed polyacrylamide (HPAM) based polymer solutions?
  • The experimental studies on evaluating the performance and stability of polymers were investigated by performing long-term thermal stability and mechanical degradation tests. Thus, comprehensive rheological studies with partially hydrolyzed polyacrylamide (HPAM) based polymer solutions were designed for defining suitable polymer solution.
  • Are acrylamide polymers thermally stable?
  • Traditional synthetic polymers such as partially hydrolyzed polyacrylamide (HPAM) are not thermally stable. At temperatures above 60°C, acrylamide moieties hydrolyze to sodium acrylate which ultimately leads to precipitation and total viscosity loss. Thermal stability can be improved by incorporating monomers such as ATBS or NVP.
