  • Ionically balanced polyacrylamide compositions ...

    2007-5-16 · Typically, the anionic polyacrylamide would have a charge of 1 to 19%, preferably 2 to 10%. Dependent on the anionic charge, the amount of balancing agent is determined. For example, a 29% anionic charges may need 20T balancing agent and a 5% anionic charge may need 7% balancing agent.
