| Abstract: | A new 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 NMR and elemental analysis. The thermal behavior was evaluated by DSC and TG, the high residue of PAPPP is due to the presence of nitrogen and phosphorus in the same mainchain. Nitrogen appears to have a somewhat synergistic flame retardant effect with phosphorus. PET samples containing 5% and 10%(mass ratio) PAPPP have limiting oxygen index values of 28.2 and 33.4. It may be concluded that nitrogen containing polyphosphonate possesses superior flame retardancy. |
