Process for preparing polyphosphazene polymers containing fluoroalkoxy and/or aryloxy substituents |
| abstract |
A process for preparing polyphosphazene polymers containing fluoroalkoxy and/or aryloxy substituents is provided. The process involves the reaction of a fluoroaliphatic alcohol or a substituted or unsubstituted aromatic alcohol or mixture of such alcohols with sodium hydroxide in an organic solvent or mixture of organic solvents which under appropriate conditions will form an azeotrope with water produced by the reaction. Water produced by the reaction is removed from the reaction mixture by azeotropic distillation thereby producing substantially dry sodium salts of said alcohols. The substantially dry sodium salts of the alcohols are then reacted with a linear polydichlorophosphazene polymer to produce polyphosphazene polymers containing fluoroalkoxy and/or aryloxy substituents. |
