  • Method of improving adhesion between a fluoropolymer and a substrate
    Patent number: 6080487
    Abstract: A multi-layer article comprising a substrate and a dehydrofluorinated fluoropolymer, wherein the dehydrofluorinated polymer contains substantially no grafted adhesion-promoting groups, and the dehydrofluorinated fluoropolymer contains sufficient carbon-carbon unsaturation to increase the adhesion between the dehydrofluorinated fluoropolymer and the substrate.

  • Aqueous dehydrofluorination method
    Patent number: 5733981
    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.
