Two anionic soluble monomers, mono(2-methacryloyl oxyethyl)acid phosphate and vinylsulfonic acid sodium salt, were grafted onto chitosan to obtain copolymers with zwitterionic property. Graft reaction improved the antimicrobial activities of chitosan. Antimicrobial activities of chitosan and graft c
## Abstract Graft chitosan derivatives (CMCTSβ__g__βMAAS and CMCTSβ__g__βAAS) were prepared by the graft copolymerization of methacrylic acid sodium (MAAS) and acrylic acid sodium (AAS) onto the etherification product of chitosanβcarboxymethyl chitosan (CMCTS). Their antioxidant activity was estima
