Product Description
Polyacrylamide is a water-soluble, high-molecular-weight polymer produced by the polymerization of acrylamide monomers or by copolymerization with other monomers. Its molecular structure contains numerous amide groups, and through chemical modification, carboxyl, quaternary ammonium, and other functional groups can be introduced to produce anionic, cationic, or nonionic variants.
