  • Properties of Polyacrylamides - polymerdatabase.com

    2020-7-11 · Very few other polyacrylamides have found industrial applications. Noteworthy are poly (N,N-dimethylacrylamide) (PDMA), poly (dimethyldiallylammonium chloride) (PDMDAAC), and poly (acrylooxyethyltrimethyl ammonium chloride) (PDAC) and copolymers thereof. PDMDAAC and PDAC are cationic polymers that can break emulsions and induce flocculation.
