摘　　要：以硝酸铈铵盐为引发剂、十二烷基苯磺酸钠为乳化剂,通过反相乳液体系引发短梗霉多糖与5个偶氮苯衍生物的乙烯基单体接枝共聚,通过FTIR、SEM、XRD对接枝共聚物结构进行了表征,并通过UV-Vis光谱研究了接枝共聚物的光致变色行为。The graft copolymerization of 5 vinyl monomers and Pullulan were carried out using Ce（ NH4 ）2 （ NO3 ）2 as initiation system, sodium do- decyl benzene sulfate as emulsifier in inverse emulsion system. The evidence and characterization of Pullulan copolymers were researched by means of FTIR spectroscopy, scanning electron microscopy （SEM） and X- ray diffsaction analysis. The photochromism of 5 graft copolymer of Pullulan with Azobenzene were investigated in solutions by UV- Vis spectroscopy.
