Fluorinated Polyether Network Polymers.

The invention relates generally to epoxy and urethane resins and more particularly fluorinated epoxy and urethane resins. The preparation of these fluorinated polymers require hexafluoropentanediol as a precursor. This compound is both scarce and expensive. Consequently, the extent of use of these valuable fluorinated polymers is restricted by the cost and difficulty of their preparation. It is therefore an object of this invention to provide fluorinated polyol and epoxy polymers which do not require an expensive and scarce precursor. Another object of this invention is to provide fluorinated epoxy and urethane resins having exceptional heat, light, and chemical resistance and a low surface energy.
