| Abstract: | A number of perfluoro polymers were heated at a constant rate of temperature rise in an atmosphere of nitrogen or air, and the volatile degradation products were passed into an aqueous solution, where the F? ions produced were monitored with a fluoride ion-selective electrode. Compounds giving rise to F? ions were formed in both nitrogen and air, but in larger amounts in the latter atmosphere. For the formation of appreciable quantities of F? ions, temperatures greater than 500°C were normally necessary. |
