Paper Title:
Relationship between Flame-Retardant Property and Structure of Cyclomatrix Phosphazene Polymer
  Abstract

A novel phosphazene cyclomatrix network polymer was synthesized via nucleophilic displacement of activated nitro groups of tri(4-nitrophenoxy)tri(phenoxy) cyclotriphosphazene with the hydroxyls of bisphenol A. Then, thermal properties of the polymer was investigated using dynamic thermogravimetric analysis (TGA) in air, pyrolysis and combustion experiments. According to the relation among the pyrolysis residue (CR) at 850°C, the char-forming tendency (CFT) of every structural unit in polymer and the limiting oxygen index (LOI), CFT of the structural unit (-P=N-)3 and the LOI of the polymer were calculated as 35.04 and 34.3 respectively, which provided theoretical parameter for designing the cyclomatrix- or cyclo- phosphazene polymers with highly thermal and flame-retardant properties.
