Summary: | The two principal objective of this research are to determine the effect of fluorine and fluorine content on the thermal and oxidative stability of polyester laminating resins; and to investigate the preparation of perfluoroglutaronitrile, perfluoroadiponitrile, the corresponding imidine and amidine, and rigid polymers derived therefrom. Polyesters have been synthesized from fluorinated glycols and the corresponding hydrocarbon glycols. Laminates prepared from these polyesters have been aged at elevated temperatures and their physical properties measured before and after aging. In general, the fluorinated polyester laminates exhibit much better retention of physical properties than their hydrocarbon analogs. The report also contains a description of synthetic work directed toward the preparation of fluorine-containing compounds used in the preparation of polyesters and as crosslinking monomers. The preparation and polymerization of perfluoroglutaronitrile is described. The polymerization of perfluoroglutarimidine and perfluoroadipamidine has been investigated. Research on the synthesis of certain novel or unusual fluorine containing intermediates considered desirable for polymerization in this project was also performed.
