Modifications chimiques de lʹhexachlorocyclotriphosphazene-Preparation de retardateurs de flame et de materiaux polymeres ignifuges ecologiques (Chemical modification of hexachlorocyclotriphosphazene - Preparation of flame retardants and ecological flame

An overview of recent developments of the chemistry of halogen-free cyclotriphosphazene is presented in this paper. The polymers or reactive monomers containing cyclotriphosphazene are inherently flame retarding with P and N elements. They can be used on their own or added to current bulk commercial polymers to enhance flame retardancy. The chemical modification of cyclotriphosphazene is discussed along with thermal stability and flame-retardant properties of the subsequent materials.
