| 摘 要： | 本文研究了十二种不同取代基的芳香族腈在Lewis酸-金属体系催化下的聚合反应。结果表明, 取代基的吸电子能力越强, 聚合反应速率越快。其速率常数与Hammett方程中的取代基特性常数σ值呈线性关系, 此外, 对聚合物的结构也进行了测定。

| Abstract: | The polymerisation of 12 aromatic nitriles catalyzed by Lewis acid-metal systems was studied. The polymerisation rate was greatly enhanced when an electron-withdrawing group was substituted in aromatic nitriles. The polymerisation rate constants were proportional to the Hammett constant of substituted group. The products obtained using CuCl2-Zn catalyst systems were mostly cyclic trimers. |
