Poly(acrylamide-co-acrylic acid) and its sodium salts (APAM) are widely used as thickening agent, binder, super absorbent, soil conditioner, filtering aid, flocculating agent, crosslinker, suspending agent, lubricant, and oil recovery agent.
Cationic polyacrylamides (CPAM) are used for emulsion breaking, and for promoting filtration and sludge dewatering.
Another common use is oil extraction and recovery. When water is injected into the well, PAM assists in pushing oil locked in reservoirs towards the pump by increasing the viscosity of the injected water.
Another low volume but important use of anionic and cationic polyacrylamides is gel electrophoresis for macromolecule separation.| Polyacrylamide | ||||||
