Synthesis and thermal performance of poly(cyclotriphosphazene- acetylferrocene) derivative

Abstract

Amino nucleophilic reagents were prepared by using acetylferrocene and diamines and then the iron-phosphazene derivative was first synthesized by the nucleophilic substitution reaction of hexachlorocyclotriphosphazene and the amino nucleophilic reagent. FT-IR curve proved that the aim product was synthesized and the chlorine atom of iron-phosphazene derivative did not completely replaced. The thermal performance of the iron-phosphazene derivative was examined by TGA. This suggests that the iron-phosphazene derivative began to degrade at 200 °C and still has 25 % residue at 700 °C. The residues morphology of the iron-phosphazene derivative was also examined. The surface of residues was smooth, fibrous arrangement and has a certain orientation structure. EDS confirmed that the main components of the higherature calcined residues were C, P and Fe.
