Some model reactions were studied to determine the optimized reaction conditions and suitable monomer structure for the reaction constructing two amide linkages successively between two monomers. Then, the route for the synthesis of the monomer was established, and its polymerization was investigated. When metal hexamethyldisilazides were used as a base, the polymerization was inhibited due to the side reaction in which the polymerizable group was decomposed by the reaction of the base. However, we found that the side reaction was suppressed by the used of a base with low nucleophilicity.

通过对一些模型反应的研究，确定了在两个单体之间连续构建两个酰胺键的反应的最佳反应条件和合适的单体结构。确定了该单体的合成路线，并对其聚合反应进行了研究。当使用金属六甲基二硅基叠氮化物作为碱时，由于其中可聚合基团被碱的反应分解的副反应，聚合被抑制。然而，我们发现使用低亲核性的碱抑制了副反应。
