| Abstract: | Various polyamides containing s-triazine rings in the main chain were synthesized by high temperature polycondensation of 2-(N-piperidino)-4,6-bis(naphthoxy-2-carbonyl chloride)-s-triazine PNCCT] with various aromatic diamines such as 4,4′-diaminodiphenyl DADP], 4,4′-diaminodiphenylamide DADPA], 4,4′-diaminodiphenylsulphone DADPS], 4,4′-diaminodiphenylsulphonamide DADPSA], 4,4′-diaminodiphenyl methane DADPM], 2,4-diamino toluene DAT] and p-phenylene diamine PPDA]. All the polyamides were characterized by viscosity measurements, IR spectra, NMR spectra, and thermogravimetric analysis. |
