Abstract: Anew polyazophosphonate, polyazodiphenylene phenylphosphonate(PAPPP) was obtained by the interfacial polycondensation of phenylphosphonic dichloride with 4,4-dihydroxyazobenzene. The structure of the polymer was confirmed by FTIR, 1H NMR, 31 P NMRand elemental analysis. The thermal behavior was evaluated by DSCand TG, the high residue of PAPPPis due to the presence of nitrogen and phosphorus in the same mainchain. Nitrogen appears to have a somewhat synergistic flame retardant effect with phosphorus. PETsamples containing 5% and 10%(mass ratio) PAPPPhave limiting oxygen index values of 28.2 and 33.4. It may be concluded that nitrogen containing polyphosphonate possesses superior flame retardancy.

Key words: Polyaphosphonate ester, Flame retardancy, Interfacial polycondensation
