  • 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.
  • Can Pam/HPAM polymers be applied in high-temperature/high-salinity reservoir conditions?
  • In order to apply PAM/HPAM polymers in high-temperature/high-salinity (HT/HS) reservoir conditions, it is important to mitigate cationic effects on hydrolysis and stability.
  • How long can a Pam polymer stay thermally stable?
  • A recent laboratory study conducted by Seright et al. indicated that a PAM polymer can remain thermally stable in the absence of dissolved oxygen and divalent cations, so that the HPAM solution is projected to maintain at least half of their original viscosity for over 8 years at 100 °C and about 2 years at 120 °C.
  • Can a dangling amide group be hydrolyzed to form an acrylic acid?
  • The dangling amide group of the PAM polymer could be hydrolyzed to form an acrylic acid that is subject to the easier interaction with cations. Chemistry regarding the amide hydrolysis is very rich and has been considered as an important modeled reaction for the enzymatic cleavage of peptide bonds , , .
