Various copolyamides were synthesized using high temperature polycondensation
technique from 2-(N-ethyl anilino)-4,6-bis(phenoxy-2-carbonyl chloride)-s-triazine [EAPCCT] and various mixtures of diamines such as; (p-phenylene diamine [PPDA]+4,4י-diaminodiphenylamide [DADPA]), (PPDA+4,4י-diaminodiphenylsulphonamide [DADPSA]), (ethylene diamine [EDA]+DADPA), (EDA+DADPSA), (EDA+1,4-diamino toluene [OAT]) etc. They were characterized by density and viscosity measurements, FTIR and NMR spectroscopy, techniques solubility tests and thermogravimetric analysis method. Density of different
copolyamides was in the range of 1.155-1.232 g/cm3. Reduced viscosity was in the range of 0.430-0.386 g/dL that indicates the fairly higher molecular weight range of the synthesized polymers, which is required for the polymer to possess reasonably good mechanical and thermal properties. All the polymers synthesized showed moderate
to high thermal stability required to be categorized as high performance materials
