Phosphazenes
Phosphazenes can be effective flame retardants. (RDC 7/20/2009) “A phosphazene is any of a class of chemical compounds in which a phosphorus atom is covalently linked to a nitrogen atom by a double bond and to three other atoms or radicals by single bonds. Two examples are hexachlorocyclotriphosphazene and bis(triphenylphosphine)iminium chloride. Phosphazenes are also known as aminophosphoranes and phosphine imides.” (Wikipedia 7/20/2009)
