Method for decomposing fluorine-containing polymers

Abstract

A method for decomposing a fluorine-containing polymer that can decompose a fluorine-containing polymer while suppressing generation of impurities after the decomposition reaction. A method for decomposing a fluorine-containing polymer, including a decomposition step including reacting a fluorine-containing polymer in subcritical water that is at a temperature of 180° C. or higher and lower than 250° C. and that contains at least one basic compound selected from the group consisting of alkali metal hydroxides and alkaline earth metal hydroxides at a concentration of 0.5 M or lower.
