Claims
- 1. A method for the polymerization of a phosphazene monomer comprising establishing and maintaining a contained zone of ionized gas plasma at an energy of less than 100 eV by applying an electric field, said gas plasma being in contact with the surface of a non-vapor volume of said phosphazene monomer to cause it to polymerize.
- 2. The method of claim 1 in which the structural formula of said phosphazene polymer product is the following: ##STR4## wherein n=the number of repeating units, and Y and Z are selected from the group consisting of chloride, bromide, fluoride, OR, NHR, NR.sub.2, and R, wherein R is an aliphatic or aromatic group, and mixtures thereof.
- 3. The method of claim 1 in which said phosphazene monomer is in crystalline solid form during plasma contact.
- 4. The method of claim 1 in which said phosphazene monomer comprises dichlorophosphazene.
