摘要
用硫酸铈铵盐和过硫酸钾－亚硫酸氢钠为引发剂，十二烷基苯磺酸钠为乳化合剂，考察了单体浓度、不同引发体系及引发剂浓度、聚合温度、聚合时间、壳多糖浓度对丙烯酸丁酯壳多糖接枝共聚反应的影响，用红外光谱和Ｘ－射线衍射对接枝共聚物结构进行了表征。
The emulsion graft copolymerization of butyl acrylate on chitosan was studied using Ce4+ / KPS as an initiator and sodium dodecy benzene salfonate as emulsifier. The effect of different emulsion graft copolymerization conditions such as KPS/Ce4+mol ratio, BA and chitosan concentrations, reaction time and reaction temperature on the percentage of graft and efficiency of graft was investigated. The grafted copoly_mer was identified by IR and X-ray diffraetion diagrams.
