  • 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 thickening affect rheological behavior?
  • Due to the salt-out effect, the solubility of polymer molecules was weakened as NaCl concentration rises, leading to the precipitation of hydrophobic groups from the aqueous phase [38 ]. Based on above results, it can demonstrate that PABC has a surprising salt-thickening property, which ispresumed to affect the rheological behaviors.
  • Why does PABC solution have a higher viscosity at 50 g/L NaCl?
  • Theaverage hydrodynamic diameters in 50 g/L NaCl are significantly larger than these in 0 and 200 g/L NaCl. This is the reason why PABC solution has a higher viscosity at 50 g/L NaCl than others NaCl concentrations in the previous viscosity measurements.
  • Does NaCl increase molecular hydrophobicity in copolymer PABC?
  • Conclusions Copolymer PABC was successfully synthesized by using a novel twin-tailed hydrophobic monomer and its solutions in NaCl show interesting thickening behaviors. The CAC shows a decline caused by the introduction of NaCl, leading to theenhancement of molecular hydrophobicity.
