  • What is partially hydrolyzed polyacrylamide (PHPA)?
  • Partially hydrolyzed polyacrylamide (PHPA), consisting of neutral acrylamide and anionic acrylate groups, is suitable for use in water with <25,000 mg/L TDS 12, 15.
  • How does PHPA affect fluid rheology?
  • The introduction of higher molecular weight synthetic polymers typified by partially hydrolysed polyacrylamide (PHPA) allowed the same effect on fluid rheology to be achieved at much lower additive concentrations, a major practical advantage.
  • What is a PHPA molecule?
  • The molecule of this polymer is a flexible chain which remains in coil-like structure in the absence of a shearing effect. The application of PHPA is limited due to high temperature and salinity (Uddin et al. 2002 ).
  • What is hydrolyzed polyacrylamide (HPAM)?
  • Hydrolyzed polyacrylamide (HPAM), a derivative resulting from the hydrolysis of PAM, demonstrates significant thickening capabilities in freshwater and at relatively lower temperatures (<75 °C) due to strong intra- and inter-chain electrostatic repulsion of carboxylate groups 14.
