通过C-N偶联反应合成了具有良好溶解性的新型耐热N取代聚苯并咪唑酰亚胺（PBII）。进行模型反应以帮助确定聚合的最佳反应条件并阐明聚合物的化学结构。通过傅里叶变换红外和元素分析对所得聚合物的结构进行了表征；结果显示与提议的结构非常吻合。所得PBII表现出高玻璃化转变温度（Tg> 290oC）和良好的热稳定性（T5%> 440oC）。 PBII 聚合物在空气中的热行为表明它们可以被视为一类新型高性能聚酰亚胺。 © 2016 中国化学工业学会
Novel heat‐resistant N‐substituted poly(benzimidazole imide)s (PBIIs) with good solubility were synthesized via a C − N coupling reaction. A model reaction was carried out to assist in determining the optimal reaction conditions for the polymerization and to elucidate the chemical structures of the polymers. The structures of the resulting polymers were characterized by means of Fourier transform infrared and elemental analysis; the results showed good agreement with the proposed structures. The resulting PBIIs exhibited high glass transition temperatures (Tg> 290oC) and good thermostability (T5%> 440oC). The thermal behavior in air of the PBII polymers suggests that they can be considered as a new class of high performance polyimides. © 2016 Society of Chemical Industry
