Novel Copolyamides Based on s-Triazine Derivatives

摘要

Ten copolyamides have been synthesized by polycondensation of 2-(N-methylpipera-zine)-4,6-bis(2-naphthoxy-6-carbonyl chloride)-s-triazine [MPNCCT] and different mixtures of diamines such as; 4,4'-diamino diphenylamide [DADPA] + 4,4'-diamino diphenyl sulphone [DADPS]; 4,4'-diamino diphenylamide [DADPA] + 4,4'-diamino diphenylmethane [DADPM]; 4,4'-diaminodiphenylamide [DADPA] + p-phenylene diamine [PPDA]; 4,4'-diaminodiphenylamide [DADPA] + ethylene diamine [EDA]; 4,4'-diaminodiphenylamide [DADPA] + 2,4-diamino toluene [DAT]; 2,4-diamino toluene [DAT] + 4,4'-diaminodiphenyl sulphone [DADPS]; 2,4-diamino toluene [DAT]+ 4,4'-diaminodiphenyl sulphonamide [DADPSA]; 2,4-diamino toluene [DAT] + 4,4'-diamino-diphenyl methane [DADPM]; 2,4-diamino toluene [DAT] + o-phenylene diamine [OPDA] and p-phenylene diamine [PPDA] + 4,4'-diaminodiphenyl sulphonamide [DADPSA]. All the copolyamides have been characterized by IR spectra, NMR spectra, solubility, density, viscosity measurements and thermogravimetric analysis [TGA]. The obtained products, have high thermal stability along with good solubility in organic solvents.
