Abstract:A series of amphoteric cellulosic graft copolymers, containing anionic carboxymethyl and cationic quaternary ammonium groups, were prepared by the graft copolymerization of carboxymethylcellulose(CMC) with dimethyldiallylammonium chloride(DMDAAC) using potassium permanganate/sulphuric acid initiation system under different conditions.Major factors affecting the polymerization reaction,such as the degree of substitution(DS) of CMC, the amount of DMDAAC, acid concentration and the amount of initiator, were studied, and the mechanism for grafting of DMDAAC onto CMC using the KMnO 4/H 2SO 4 redox system was elucidated.
Keywords:amphoteric cellulosic graft copolymers  carboxymethylcellulose  dimethyldiallylammonium chloride  graft copolymerization
