A series of new poly(amide-imide)s was prepared by polycondensation of our already reported diamine, N,N’-[((propane-2,2-diylbis(4,1-phenylene) bis(oxy))bis(4,1-phenylene)]bis(4-aminobenzamide) (BDM) containing flexible ether and amide linkages with different aromatic dianhydrides via simple two-step method. The synthesized poly(amide-imide)s were characterized by FTIR spectroscopy and elemental analysis. These poly(amide-imide)s demonstrated nice solubility in most of the organic solvents at ambient temperature and upon heating. They also revealed great thermal stability and showed glass transition temperatures (Tgs) exceeding 150 °C in addition to the temperature of 10% weight loss (T₁₀) that fluctuated from 460 to 522 °C having more than 59% residual yield at 800 °C in nitrogen atmosphere indicating their flame retardant characteristics. Furthermore, they also showed interesting photoluminescent properties with blue green solution emission properties, redox activity, and lower onset oxidation potentials with appreciably shallow HOMO levels.

通过我们已经报道的二胺N，N' -[（（丙烷-2,2-二基双（4,1-亚苯基）双（氧基）））双（缩合）的缩合反应制备一系列新的聚（酰胺-酰亚胺）简单的两步法将具有柔性醚和酰胺键且具有不同芳族二酐的4,1-亚苯基]]双（4-氨基苯甲酰胺）（BDM）进行了FTIR光谱和元素分析表征了合成的聚酰胺（酰亚胺）这些聚（酰胺-酰亚胺）在环境温度和加热条件下对大多数有机溶剂表现出良好的溶解性，还表现出出色的热稳定性，除10°C的温度外，玻璃化转变温度（Tgs）超过150°C。体重减轻百分比（T ₁₀）在460至522°C之间波动，在氮气氛中于800°C时残留产率超过59％，表明其阻燃特性。此外，它们还显示出有趣的光致发光特性，具有蓝绿色溶液的发射特性，氧化还原活性和较低的HOMO含量，且起始氧化电位较低。
