摘　　要：通过三步反应合成了一种含咪唑的邻苯二甲腈的模型化合物(BIPN),同时合成了一种不含咪唑的邻苯二甲腈的模型化合物(Biphenyl-PN)用于对比。通过热重分析(TGA)、紫外光谱、热处理前后的红外光谱(FT-IR)、核磁共振氢谱(1H-NMR)对比研究了这两种化合物的结构和性能,并初步研究了BIPN的固化机理。结果表明:BIPN具有自催化作用,其固化过程中有酞菁环和三嗪环生成,且主要结构为三嗪环。A benzimidazole-containing phthalonitrile model compound（BIPN） was synthesized by three-step reaction and another phthalonitrile model compound（Biphenyl-PN） was synthesized for comparison.The structure and performance of these two compounds were investigated by comparison of their thermal gravimetric analysis（TGA）,ultraviolet spectroscopy,infrared spectroscopy（FT-IR）before and after heat treatment and hydrogen nuclear magnetic resonance spectrum（1H-NMR）.The curing mechanism of BIPN was studied.The results showed that,BIPN had a self-catalytic role in the curing process.The phthalocyanine ring and triazine ring were generated during the curing process and the triazine ring was the main structure.
