New series of aromatic poly(ether ether ketone amide)s were synthesized by low-temperature solution polymerization of novel aromatic diamine, namely 1,3-bis-4′-(4″-aminophenoxy benzoyl)benzene (XIV), and aromatic diacid chlorides, viz. isophthaloyl chloride (IPC) and terephthaloyl chloride (TPC). Co-poly(ether ether ketone amide)s were also synthesized by employing various mole proportions of IPC and TPC with diamine (XIV). These poly(ether ether ketone amide)s were characterized by FTIR, solubility, inherent viscosity, TGA, DSC, and XRD. Inherent viscosities of these poly(ether ether ketone amide)s were in the range of 0.41–0.52 dL/g in DMAc, indicating the formation of moderate to high molecular weight of polymers. Poly(ether ether ketone amide)s showed good solubility in polar aprotic solvents such as N , N -dimethyl acetamide (DMAc), N -methyl 2-pyrrolidone, N , N -dimethylformamide, and dimethyl sulfoxide. These poly(ether ether ketone amide)s had glass transition temperatures, as determined by DSC, in the range of 252–302 °C. These polymers showed similar decomposition patterns and had no weight loss below 335 °C, and temperatures for 10% weight loss ( T 10 ) were in the range of 397–406 °C, indicating that these polymers showed good thermal stability.

苯氧基和 1,3 酮部分键合修饰的可加工芳香族聚（醚醚酮酰胺）的合成和表征

新型芳香族二胺1,3-双-4′-(4″-氨基苯氧基苯甲酰基)苯(XIV)和芳香族二酸通过低温溶液聚合合成了一系列新的芳香族聚醚醚酮酰胺氯化物，即。间苯二甲酰氯 (IPC) 和对苯二甲酰氯 (TPC)。还通过使用不同摩尔比例的 IPC 和 TPC 与二胺 (XIV) 合成共聚（醚醚酮酰胺）。这些聚（醚醚酮酰胺）通过 FTIR、溶解度、特性粘度、TGA、DSC 和 XRD 进行表征。这些聚（醚醚酮酰胺）在 DMAc 中的固有粘度在 0.41–0.52 dL/g 的范围内，表明形成了中等至高分子量的聚合物。聚（醚醚酮酰胺）在极性非质子溶剂如 N，N-二甲基乙酰胺（DMAc）中表现出良好的溶解性，N-甲基2-吡咯烷酮、N，N-二甲基甲酰胺和二甲亚砜。这些聚（醚醚酮酰胺）的玻璃化转变温度，由 DSC 测定，在 252–302 °C 的范围内。这些聚合物显示出相似的分解模式，并且在 335 °C 以下没有重量损失，10% 重量损失的温度 (T 10 ) 在 397–406 °C 的范围内，表明这些聚合物显示出良好的热稳定性。
