  • What is the role of electrolyte salt in hydrophobic acrylamide-based polymers?
  • Addition of small amount of electrolyte salt to aqueous solution of hydrophobically modified acrylamide-based polymers helps to increase the solution polarization, and reinforcing the hydrophobic association , .
  • Is polyacrylamide hydrolyzed?
  • Among the numerous results, polyacrylamides (PAM) were widely used because they can increase the viscosity of the displacing phase while reducing the water/oil mobility ratio so as to enlarge the swept volume , . However, PAM is easily hydrolyzed and did not show temperature, salt, and shear resistances , , .
  • How does NaCl concentration affect PABC's salt-thickening properties?
  • Salt-thickening properties of PABC in NaCl solution The CAC at which apparent viscosity of the polymer solution shows a rapidly rising trend reflects the thickening property of HMPAM. Fig. 4 A depicts the CAC as a function of NaCl concentration.
  • Does salt and temperature affect the viscosity of a novel functional polymer?
  • The influence of salt and temperature on the viscosity of a hydrophobically modified polyacrylamide-based (PAM-based) novel functional polymer (RH-4) was investigated. To study the viscosifying mechanism in brine solution, scanning electron microscope (SEM) was applied to observe the network microstructures of polymer solution.
