摘　　要：经过Diels-Alder反应等步骤制备了新型马来酰亚胺单体--甲基丙烯酸-4-(呋喃-马来酰亚胺乙基)酯(MMA-FMI),经过重氮、偶合等步骤制备了新型含呋喃环的偶氮苯单体--甲基丙烯酸-4-(4-呋喃-2-甲基-2-乙酸酯基偶氮)苯酯(MMA-FAzo),MMA-FMI、MMA-FAzo再与甲基丙烯酸-4-(4-甲氧基偶氮)苯酯(MMA-Azo-OCH3)无规共聚得到含可加成反应偶氮苯聚合物(PAzo)。采用核磁共振氢谱、傅里叶变换红外光谱、凝胶渗透色谱对聚合物结构进行表征;使用紫外-可见分光光度计研究聚合物的顺反异构化行为,发现聚合物的光致顺反异构化速率常数为0.217 s-1,聚合物PAzo具有快速光响应性能;通过热失重分析仪研究聚合物的可加成特性;通过热可逆实验证明,交联的聚合物仍具有可回收与再加工性。A novel maleimide monomer 4-(furan-maleimide ethyl) methyl methacrylate(MMA-FMI)was prepared by Diels-Alder reaction. A novel azobenzene monomer with furan,4-(4-furan-2-methyl-2-acetate azo) phenyl methyl methacrylate(MMA-FAzo), was prepared by nitro reduction, diazotization, coupling. MMA-FAzo was randomly copolymerized with MMA-FMI and 4-(4-methoxy azo) phenyl methyl methacrylate(MMA-Azo-OCH3) to obtain an additive reaction azobenzene polymer(PAzo). The structure of the polymer was characterized by nuclear magnetic resonance specteoscopy, Fourier infrared spectroscopy, gel permeation chromatography. The photoinduced cis-trans isomerization behavior of the polymer was characterized by UV-Vis absorption spectrometer. By UV-Vis absorption spectrometer, the constant of photoinduced cis-trans isomerization rate is 0.217 s-1, indicating that the PAzo is rapid light-response. the additive property of the polymer was analyzed by TGA. By the thermoreversible experiment, the crosslinked PAzo is recyclable and reprocessed.
