Abstract: Mono acrylic quaternary ammonium salt was prepared by the continuous reaction of acrylic acid with 2-( chloromethyl) and N, N-dimethyl ethanolamine. Maleic anhydride was reacted with triethanolamine to produce diol with inner quatemary ammonium salt, which could be used to react with IPDI, PEG 400 and 2-hydroxyethyl methacrylate to form acrylate blocked polyurethane quaternary ammonium salts. The triacrylate blocked carbamate formed by reaction of triethanol amine, IPDI and 2-hydroxyethyl methacrylate was reacted with tetrafluoboric acid and hydrochloric acid to give trifunctional quaternary ammonium salts. The structure of quatemary ammonium salts were characterized by IH-NMR and FT-IR.The composites containing above quaternary ammonium salts cured quickly and its film showed excellent antistatic property and water washability.
