Abstract
Various copolyamides have been synthesized from 2-(N-β-naphthylamine)-4,6-bis-(naphthoxy-3-carbonylchloride)-s-triazine [NANCCT] with each of the mixture of diols: 4,4′-diaminodiphenyl (DADP)+4,4′-diaminodiphenyl methane (DADPM), DADP + 4,4′-diaminodiphenyl amide (DADPA), DADP+4,4′-diaminodiphenylsulfonamide (DADPSA), DADP+4,4′-diaminodiphenyl sulfone (DADPS), DADP+2,4-diaminotoluene (DAT), DADP+p-phenylenediamine (PPDA), DADP+ethylene diamine (EDA), EDA+DADPM, EDA+DADPA, EDA+DADPSA, EDA+DADPS, EDA+DAT, EDA + PPDA. All polyamides were characterized by various physicochemical properties such as yield, color, solubility, density, viscosity, temperature characteristics, activation energy of thermal decomposition, IR spectra and NMR spectra.
