Polymers of N,N-diallyldimethylammonium salts have been commercially important for their use in water treatment, bio-materials, ion exchange resins, and paper additives. Synthesis of N,N-diallyammonium salt polymers has been shown to proceed smoothly by free radical cyclopolymerization wherein 5 membered ring, cationic repeat units are formed. Herein we report the preparation of hydrophobic-hydrophilic block copolymers containing polysulfone and either poly(N,N-diallyldimethylammonium chloride) (PDADMAC) or poly(N,N-diallylpiperdinium chloride) (PDApipCl). Polysulfone was terminally functionalized with a radical initiator and block copolymers were then synthesized by the free radical cyclopolymerization of the N,N-diallyammonium salt in the presence of the polysulfone macroinitiator. The presentation will describe the amphiphilic block copolymer preparation, and the characterization of the membranes produced.
