Abstract: A novel aromatic diamine, 2,5-bis-[4”-aminobenzyl)-4’-benzamide]-3,4-diphenyl thiophene (BATP) containing bulky tetraphenyl thiophene group, methylene spacer and preformed amide linkage was synthesized and characterized by FT-IR, NMR (1H, 13C, DEPT 13C) and Mass spectrometry. A series of novel aromatic poly(amide-azomethine)s was successfully prepared by solution polycondensation of BATP with aromatic dialdehydes, namely isophthalaldehyde (IPA) and / or terephthaldehyde (TPA) in different mole % proportions. All the poly(amide-azomethine)s were characterized by FT-IR spectroscopy, viscosity measurements, solubility tests, differential scanning calorimetry (DSC), thermogravimetric analysis (TGA) and X-ray diffraction (XRD). The results of characterization shows that these polymers meet high temperature resistant requirements so could find applications as special materials in aerospace, military and microelectronics industries.
