polyacrylamide vs acrylamide function

  • Difference Between Acrylamide and Polyacrylamide |

    Poly (acrylamide) (PAA), a synthetic polymer, is widely used as a flocculent, a paper strengthening agent, and can also be applied to enhance the recovery of oil [128]. Moreover, PAA is a water-soluble polymer of biomedical and pharmaceutical interest widely studied as a hydrogel for blood compatible material [129].
