D. Gomes, S. P. Nunes, J. Carlos Pinto, and C. Borges. Synthesis and characterization of flexible polyoxadiazole films through cyclodehydration of polyhydrazides. Polymer, 44(13) 3633-3639, June 2003. [Pg.344]

Polydithiazoles Polyoxadiazoles Polyamidines Pyrolyzed polyacrylonitrile Polyvinyl isocyanate ladder polymer Polyamide-imide Polysulfone Decompose at 525°C (977°F) soluble in concentrated sulfuric acid. Decompose at 450-500°C (842-932°F) can be made into fiber or film. Stable to oxidation up to 500°C (932°F) can make flexible elastomer. Stable above 900°C (1625°F) fiber resists abrasion with low tenacity. Soluble polymer that decomposes at 385°C (725°F) prepolymer melts above 405° C (76l.°F). Service temperatures up to 288° C (550°F) amenable to fabrication. Thermoplastic use temperature —102°C (—152°F) to greater than 150° C (302°F) acid and base resistant. [Pg.320]

The polyoxadiazoles 14 were found to fluoresce purple-blue under ultraviolet irradiation (quantum efficiency of film 11%). The photoluminescence emission spectrum of the polymer 14b-l is shown in Figure 4. [Pg.329]
