A new series of copoly(ether‐amide‐imide)s (CoPEAIs) 7a–f were synthesized through the direct polycondensation reaction of N , N ′‐(4,4′‐diphenylether)bistrimellitimide 1 with 1,5‐naphthalene diamine 2, 3,4‐diamino benzophenone 3 in the presence of adipic acid 4, fumaric acid 5 and terephthalic acid 6 as a second diacid in a medium consisting of N ‐methyl‐2‐pyrrolidone (NMP), triphenyl phosphite (TPP), calcium chloride and pyridine (Py). The resulted polymers were fully characterized by means of Fourier transform infrared (FT‐IR) spectroscopy, elemental analyses, inherent viscosity, solubility tests and ultraviolet–visible (UV–vis) spectroscopy. Thermal properties of the CoPEAIs 7a–c were evaluated with thermogravimetric analysis (TGA) techniques and derivative of thermogravimetric (DTG) under a nitrogen atmosphere.
