Imide Cyclotriphosphazene/Hexafluoroisopropylidene Polymers

Useful physical and chemical properties observed in compounds obtained by thermally-induced melt polymerization of maleimido-phenoxy cyclotriphosphazenes linked through hexafluoroisopropylidene-diphthalimide groups. Polymers exhibit high strength, high thermal stability, and high char yields, and appear to be excellent candidates for fabricating composite materials.
