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.
