A new inherently cross‐linked polymer, polydigolphosphate, has been synthesized. The polymer has high affinity for moisture and a tendency to retain sodium chloride, which is produced as a coproduct in the synthesis of the polymer. The purity and, hence, the structural identity of the polymer have been established by combined DTA‐TG analyses in an inert atmosphere. Thermal degradation of the polymer has been quantitatively correlated on the basis of a proposed mechanism. The mechanism may serve as a representative one for the degradation of similar polyphosphates of poly(ethylene glycol). © 1993 John Wiley & Sons, Inc.
