Hexa [4-(4-hydroxy-phenyliminomethyl) phenoxy] cyclotriphosphazene (A1) and Hexa [4-(2-hydroxyphenyliminomethyl) phenoxy] cyclotriphosphazene (A2) were derived from the reactions of hexa(4formyl-phenoxy)cyclotriphosphazene and hexa(2-formyl-phenoxy)cyclotriphosphazene with 4aminophenol and 2-aminophenol. Adsorption process in an aqueous solution of Cu, Fe, Mn and Zn ions of the organophosphazenes bearing imine groups were performed depending on the initial concentration of metal ions and time. All of the compounds adsorbed the selected metal ions in the first 10 minutes. When the initial concentration of metal ions increases, the amount of metal ions adsorbed of organophosphazene with imine groups increased. Although the chemical structures of the compounds are different, the amount of adsorbed metal was about the same.

“…Although some cyclophosphazene derivatives containing Schiff bases were randomly synthesized in recent years [8,[26][27][28][29][30][31][32], their thermal stabilities and absorbance properties have not been investigated systematically. In this study, it was planned to synthesize a thermally stable new type of heterocyclic structures by combining the thermal properties of hexachlorocyclotriphosphazene and Schiff bases.…”

In this study, a series of cyclotriphosphazene derivatives containing a Schiff base (3a-3d) were synthesized by the reactions of hexachlorocyclotriphosphazene (1) with bis-aryl Schiff bases (2a-2d) having different terminal groups (H, F, Cl, and Br). The products (3a-3d) were characterized by elemental and mass analyses, FT-IR, and 1 H, 13 C, and 31 P NMR spectroscopies. Furthermore, the structure of compound 3a was also determined by X-ray crystallography. The thermal behaviors and the spectral properties of the new cyclotriphosphazene compounds (3a-3d) were investigated and the results were compared in the series.

A novel kind of polyoxometalate (POM) ‐containing Schiff based polyphosphazene microspheres (PSPMs) were successfully prepared through the polycondensation between POM‐containing polyaldehyde and 4,4′‐diaminodiphenylmethane. The PSPMs attained excellent thermal stability and demonstrated good monodispersity with a diameter of about 400 nm. In this work, the fire resistance of PSPMs was investigated in the epoxy resin (EP) matrices. Notably, the PSPMs displayed good distribution in EP matrices. Therefore, the dynamic mechanical properties of EP/PSPMs composite were enhanced. After the addition of 4 wt% PSPMs, the thermogravimetric analysis showed that the char yield at 750°C of the EP/PSPMs composite increased from 12.9 wt% (EP) to 29.0 wt% in nitrogen. And the composite attained a limiting oxygen index of 27.5% and passed the UL‐94V‐1 rating. In comparison with that of pure EP, the peak value of the heat release rate and total smoke production decreased dramatically. Meanwhile, the toxic CO gas was largely reduced due to the reduction reaction of POM during the combustion process. To further illuminate the flame‐retardant mechanism, the char residues and gaseous pyrolysis products of EP/PSPMs were examined. This work may provide a new perspective for the synthesis and application of functional metal‐containing polymer microspheres.
