Abstract :A new flame-retardant polyamide containing phosphine oxide moieties in the main chain was synthesized from the solution polycondensation reaction of bisinsert ignore into journalissuearticles values(3-aminophenyl); phenyl phosphine oxide with N,N-insert ignore into journalissuearticles values(4,4-diphenylether); bis trimellitimide, using thionyl chloride, N-methyl-2-pyrolidone, and pyridine as condensing agents. This new polymer was obtained in high yield insert ignore into journalissuearticles values(92%);, has high inherent viscosity insert ignore into journalissuearticles values(0.73 dL/g);, and was characterized by elemental analysis, FT-IR spectroscopy, thermal gravimetric analysis insert ignore into journalissuearticles values(TGA and DTG);, and solubility testing. Furthermore, another polyamide was prepared by the solution polycondensation reaction of N,N-insert ignore into journalissuearticles values(4,4-diphenylether); bis trimellitimide with 1,4-phenylene diamine, and its flame-retardant behavior was compared to that of the previous one.
