The production phase of the program was completed during the previous quarterly period. The present emphasis is toward the preparation of fluorinated aliphatic and aromatic nitroso compounds with functional groups and their terpolymerization with CF3NO and C2F4 to polymers which may be cured through the functional groups. New methods were explored to prepare nitroso-perfluoroaliphatic and nitrosoperfluoroaromatic acids and, as a result, the new compound - 4-nitroso-2,3,5,6-tetrafluorobenzoic acid - was synthesized. Terpolymers were prepared containing the functional monomers vinylidene fluoride, trifluoroethylene, acrylic acid, and 4-nitroso-2,3,5,6-tetrafluorobenzoic acid. Curing studies were carried out on vinylidene fluoride and trifluoroethylene terpolymers.
