    Partially Hydrolyzed Polyacrylamide Ion Polymers

    Hydrolyzed polyacrylamide is an anionic polyelectrolyte, carriying plenty of negative charges along the polymer chain. Although polyacrylamide is a nonionic polymer, the hydrolysis can occur readily, converting some of the amide groups to carboxylate ions. This gives an anionic polyelectrolyte with a charge density, depending on the degree of hydrolysis and pH value of the solution. The
