SYNTHESIS AND CHARACTERIZATION OF SCHIFF-BASE-CONTAINING POLYAMIDES

A series of new Schiff base polyamides (PAs) were synthesized by polycondensation of benzilbisthiosemicarbazone diamine (LH6) with different commercially available aliphatic and aromatic diacid chlorides. The monomer and all the PAs were characterized by FTIR, 1H-NMR, and elemental analysis. The prepared polyamides showed inherent viscosities in the range of 0.30-0.36 dL/g in DMF at 25C, indicating their moderate molecular weight. The PAs were completely soluble in aprotic polar solvents such as dimethylformamide (DMF), N-methylpyrolidone (NMP), tetrachloroethane (TCE), dimthylsulfoxide (DMSO) and also in H2SO4 and partially soluble in THF, acetone and chloroform at room temperature. Thermal analysis showed that these PAs were practically amorphous and exhibited 10% weight loss above 220C.
