Title: Solid state synthesis of poly(dichlorophosphazene)

Abstract: A method for making poly(dichlorophosphazene) using solid state reactantsis disclosed and described. The present invention improves upon previousmethods by removing the need for chlorinated hydrocarbon solvents,eliminating complicated equipment and simplifying the overall process byproviding a "single pot" two step reaction sequence. This may beaccomplished by the condensation reaction of raw materials in the meltphase of the reactants and in the absence of an environmentally damagingsolvent.
