STUDY ON THE EMULSION GRAFT COPOLYMERIZATION OF BUTYL ACRYLATE ONTO CHITOSAN
壳多糖与丙烯酸丁酯的乳液接枝共聚研究

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.
