he emulsion graft copolymerization of butyl acrylate onto chitosan was investigated

using KPS/NaHSO3 as a redox initiator

sodium dodecy benzene sulfonate as emulsifier. It was found that the percentage of graft

efficiency of graft and homopolymer depended on chitosan content

KPS/NaHSO3

BA concentrations

reaction time

reaction temperature. The grafted copolymer was identified by IR

SEM

X-ray diffraction diagrams. The films formed from copolymer emulsion were tested and the results show that the elongation ratio of chitosan film will be increased by emulsion graft copolymerization with butyl acrylate.
