通过甲基丙烯酸钾盐与溴化物的反应合成了一系列柔性间隔基长度不同的甲基丙烯酸对甲氧基偶氮苯烷氧基酯（ＰＭＡＡＺＯｎ，ｎ＝２，３，４，５，６），然后聚合成相应的聚合物．用１ＨＮＭＲ和ＩＲ表征了聚合物的结构，ＧＰＣ测定了分子量，ＤＳＣ和偏光显微镜观测了液晶高分子的相行为和织构．研究了间隔基长度对织构、相变和热力学性质的影响，观测到聚合物的ＴＮＩ随间隔基的长度变化表现出的奇偶效应． A series of pMAAZOn (n = 2, 3, 4, 5, 5-dimethylamino) phenylalanyl methacrylate with different length of flexible spacer were synthesized by the reaction of potassium methacrylate and bromide. 6) and then polymerized into the corresponding polymer. The structure of the polymer was characterized by 1H-NMR and IR. The molecular weight was determined by GPC. The phase behavior and texture of the polymer were observed by DSC and polarized light microscope. The effect of spacer length on the texture, phase transition and thermodynamic properties was investigated. It was observed that the TNI of the polymer exhibited a parity effect with the change of spacer length.
