    • PURPOSE: Polyhalophosphazenes or polyorganohalophosphazenes in solution are provided in which the solution contains a solvent which stabilizes the polyhalophosphazenes or polyorganohalophosphazenes against gelation. CONSTITUTION: In accordance with an aspect of the present invention, there is provided a solution which comprises a solute and at least one solvent. The solute is a polyphosphazene. The at least one solvent includes a first solvent in an amount of at least 25% by volume of the total amount of solvent. The first solvent has the following structural formula: R1-(O-R2-)nO-R3. Each of R1 and R3 is an aliphatic or aromatic hydrocarbon having from 1 to 6 carbon atoms, and each of R1 and R3 may be the same or different. R2 is an aliphatic hydrocarbon having from 1 to 4 carbon atoms. n is from 2 to 10, preferably from 2 to 4.
