Abstract

Six new poly(amide-imide)s (PAIs) 8a-f were synthesized from the direct polycondensation reaction of 1,1-bis[4-(trimellitimido)phenoxy]methane 6 with various aromatic diamine 7a–f. The polymerization reactions produced a series of thermally stable and organosoluble PAIs with high yield and good inherent viscosity. The resulted polymers were fully characterized by means of FTIR and 1H-NMR spectroscopy, elemental analyses, inherent viscosity, and solubility tests. Also thermal properties of the PAIs 8a–f were investigated using thermal gravimetric analysis (TGA) and derivative of thermaogravimetric (DTG) analysis. dicarboxylic acid 6 was synthesized from the reaction of 1,1-bis[4-aminophenoxy]methane 4 with trimellitic anhydride 5 in a solution of glacial acetic acid/pyridine (Py) at refluxing temperature.
