反相乳液法合成含偶氮苯类光学活性侧基短梗霉多糖
Synthesis of Graft Copolymer of Pullulan with Azobenzene in Inverse Emulsion System
【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。
【Abstract】 The graft copolymerization of 5 vinyl monomers and Pullulan were carried out using Ce(NH4)2(NO3)2 as initiation system,sodium dodecyl 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.
