摘　　要：利用点击化学方法合成了一种侧链上含有肉桂酸酯基团的线性聚合物,利用核磁共振(1H NMR)、红外光谱(FTIR)、凝胶渗透色谱(GPC)和示差扫描量热分析(DSC)等方法对该聚合物的结构和性能进行了表征。DSC谱图显示,在170℃附近出现一个明显的放热峰,通过进一步的实验证明,该放热峰是由聚合物侧链上残余的叠氮基团与肉桂酸酯基团上的碳碳双键发生反应引起的。另外,实验证明,通过稀盐酸处理,可以消除聚合物中残余的叠氮基团。A linear polymer containing the cinnamate moiety was prepared by click chemistry. The chemical structure and the property of the polymer were characterized by 1H NMR, FTIR, GPC and differential scanning calorimetry （DSC）. DSC curve exhibited an obvious exothermic peak at about 170℃, and further experiments proved that the exothermie peak was attributed to the reaction between the residual azide group of the polymer and carbon-carbon double bond of the cinnamate group. Further more, it was found that the residual azide groups of the polymer could be eliminated by treatment with dilute hydrochloric acid.
