  • 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.
  • What is partial hydrolyzed polyacrylamide (HPAM)?
  • Partially hydrolyzed polyacrylamide (HPAM) is a water-soluble polymer material used in oil fields [ 18, 19 ]. It usually has a linear structure with high molecular weight [ 20] and is obtained by partial hydrolysis of PAM or by copolymerization of sodium acrylate with acrylamide [ 21 ].
  • Can silica nanoparticles improve rheological properties of partially hydrolyzed polyacrylamide?
  • This work aims to improve the rheological properties of partially hydrolyzed polyacrylamide (HPAM) for enhanced oil recovery by using silica (or silicon dioxide, SiO2) nanoparticles (NPs). Novel aq...
  • 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 ).
