摘要:
High molecular weight polyphenyl-as-triazines were prepared at ambient temperature by the cyclopolycondensation of perfluoroglutaramidrazone and perfluoroadipamidrazone with various bis(1,2-dicarbonyl) monomers. The effect which the perfluoroalkylene group had upon certain chemical and physical properties of the polymers was determined. Thermal evaluation involved TGA, DSC, TMA, and isothermal weight loss studies of films at 232 °C in air. The polymers exhibited excellent hydrolytic stability as evidenced by retention ofninhafter boiling in water (24 hr) and 10% sodium hydroxide solution (8 hr). A stable uncyclized intermediate was isolated from the reaction of perfluoroadipamidrazone and benzil which was cyclized to the phenyl-as-triazine model compound [3,3′ -perfluorotetramethylenedi (5,6-diphenyl-as-triazine)].
