THE USE OF PHOSPHAZENES AS FIRE-RESISTANT MATERIALS

A survey of the use of cyclo- and poly(phosphazenes) in fire resistant applications is presented. Where appropriate, synthesis and commercia l availability will be indicated. Two fundamentally different approach es, phosphazenes as additives or as intrinsically flame resistant mate rials, will be discussed. While the former category is limited to cycl ophosphazenes, the latter involves linear poly(phosphazenes), cyclolin ear and cyclomatrix materials and carbon chain polymers with cyclophos phazenes as substituents.
