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.
