Abstract

A process comprises exposing a composition comprising at least one fluorinated carboxylic acid to at least one degradation agent under conditions effective to decarboxylate at least 10% of the at least one fluorinated carboxylic acid. The at least one fluorinated carboxylic acid is selected from the group consisting of perfluoroalkyl carboxylic acids, perfluoroether carboxylic acids, and combinations thereof. A degradation composition includes a fluoropolymer, at least one fluorinated carboxylic acid, and at least one degradation agent.
