polyacrylamide enhanced oil recover application of Nepal
The aim of thisworkwas to compare the rheological properties in shear and extensional flow of polymer aqueous solutions: ionic polyacrylamide (Rokrysol WF2), non-ionic partially hydrolyzed
We have investigated the effect of ionic and non - ionic surfactants on the structure and rheological properties of polyacrylamide hydrogels. With addition of ionic and non-ionic surfactants, just below and above their critical micellar concentration (CMC), there is a significant decrease in hydrogels mechanical strength as compared to the parent hydrogels alone.
