Abstract

Novel diamine containing thiazole ring and double sulfide bond was synthesized, and the related polyamides were prepared by a direct polycondensation reaction of this diamine and various aromatic diacids. The polyamides were obtained in good yields and were characterized by differential scanning calorimetry, thermal gravimetric analysis, Fourier transform infrared, viscosity, solubility, and elemental analysis. The glass transition temperatures of synthesized polyamides were in the range of 120–192 °C. The inherent viscosity of these polyamides was in the range of 0.4–0.62 dL/g. The solubility of these polyamides was investigated in some solvents such as dimethyl sulfoxide, N-methyl-2-pyrrolidinone, and N,N-dimethylformamide.
