摘要
制备了3种不同结构的聚胺酰亚胺,采用差示扫描量热法(DSC)、热重分析法(TG)和傅立叶转换红外光谱(FT-IR)重点分析了3种结构聚胺酰亚胺体系中的伯胺(-NH2)、仲胺(-NH-)与碳碳双键(-C=C-)的反应及其变化情况,得出了不同结构聚胺酰亚胺的聚合反应机理。
Three different structures of polyamine-imides were prepared. The reaction and variation conditions of primary amine(-NH2), secondary amine(-NH-) and carbon-carbon double bonds(-C=C-) in the three types of polyamine-imide were analyzed by differential scanning calorimetry(DSC), thermogravimetric analysis(TG) and Fourier transform infrared spectroscopy (FT-IR), and the polymerization mechanisms of the polyamine-imides with different structures were obtained.
