    Notes: Abstract A new polyazoxyphosphonate was synthesized by reaction of 4-4′-dihydroxyazoxybenzene and dichlorophenyl phospine oxide by interfacial polycondensation using a phase transfer catalyst. The polymer was characterized and the results obtained by various analytical techniques indicate that it is mostly amorphous, low molecular weight and soluble in organic solvents such as DMF, DMAC, NMP, etc. The high char residue (∼40%) and limiting oxygen index indicate flame retardancy of the polymer which is due to phosphorus. Thermal stability of this polymer is moderate. TheT g appears to be at 152°C.

    Description / Table of Contents: Poly(phenylphosphindiylterephthaloyl), ein neues phosphorhaltiges Polymeres, wurde durch Lösungspolykondensation von Dilithium(phenyl)phosphin mit Terephthaloylchlorid bei niedriger Temperatur hergestellt. Es ist in polaren aprotischen Lösungsmitteln löslich; die inhärente Viskosität in DMF bei 30°C beträgt 19 ml/g. Das Polymere wurde mittels Elementaranalyse sowie IR- und 1H-NMR-Spektroskopie charakterisiert. TGA-Messungen ergeben, daß das Polymere in Luft bis 250°C stabil ist; es ist selbstverlöschend.
    Notes: Poly(phenylphosphinediylterephthaloyl), a novel phosphorus-containing polymer, was synthesized by low-temperature solution polycondensation of dilithio(phenyl)-phosphine with terephthaloyl chloride. The resulting polymer is soluble in polar aprotic solvents, having inherent viscosity of 19 ml/g in DMF at 30°C. The polymer was characterized by elemental analysis, IR and 1H-NMR spectroscopy. TGA data show that the polymer is stable up to 250°C in air. The polymer was found to be self-extinguishing.
