通过双(4-羧基苯基)苯基氧膦与一系列芳香族二胺的缩合反应，合成了五种新型含膦氧基的聚酰胺。用差示扫描量热法和热重分析法研究了聚合物的热性能。记录了225-254°C范围内的玻璃化转变温度，以及良好的热氧化稳定性(在>；420°C时发生5%的失重)，以及在650-800°C长期加热时的高炭产率(24-50%)。所合成的聚酰胺在非质子性极性溶剂中具有良好的溶解性。©1996 John Wiley父子公司
Five novel polyamides incorporating phosphine oxide groups have been synthesized by the condensation reaction of bis(4-carboxyphenyl)phenylphosphine oxide with a series of aromatic diamines. The thermal properties of these polymers were investigated by differential scanning calorimetry and thermogravimetric analysis. Glass transition temperatures in the 225–254°C range were recorded, together with good thermooxidative stability (5% weight loss occurring at >420°C) and high char yield upon prolonged heating at 650–800°C (24–50%). Also, good solubility in aprotic polar solvents was observed for all polyamides synthesized. © 1996 John Wiley & Sons, Inc.
