Sep 17, 2021 · Partially hydrolyzed polyacrylamide (HPAM) is the most commonly used polymer for its high viscosity in low salinity water [ 4, 5 ]. However, the viscosity is found to decrease dramatically in high salinity water. The viscosity characteristic of the polymer is influenced by the aggregation behavior.
