Several new polyphosphoramide esters have been synthesized by solution polycondensation of N,N'-bis (p-chloroformylphenyl)N"-phenylp hosphoric triamide with various aromatic diols. The polymers were characterized by i.r., 1H, 13C and 3tp n.m.r, spectroscopy and by their inherent viscosity. Thermo-oxidative stability and flammability of the polymers were evaluated by thermogravimetry and limiting oxygen index values respectively.
