  • The difference of anionic, cationic and Non-ionic ...

    2018-3-27 · March 27, 2018. Polyacrylamide is not the only acrylamide unit, the acrylamide unit is mostly called polyacrylamide. Thus, polyacrylamide may contain structural units that can be ionized or hydrolyzed in water to carry charges. As a result, there are cationic, anionic, non-ionic, amphoteric ion type of various polyacrylamide anionic polyacrylamide。.
