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 degrees C. These polymers showed similar decomposition patterns and had no weight loss below 335 degrees C, and temperatures for 10% weight loss (T-10) were in the range of 397-406 degrees C, indicating that these polymers showed good thermal stability.
