Abstract
A method of dehydrofluorinating a fluoropolymer comprising the steps of: providing an fluoropolymer emulsion comprising water, a fluoropolymer, and substantially no organic solvent; adding to the fluoropolymer emulsion a basic compound, the base compound being added at a concentration and in an mount that does not result in coagulation of the fluoropolymer; and exposing the mixture of fluoropolymer emulsion and basic compound to reaction conditions sufficient to cause dehydrofluorination of the fluoropolymer.
