A solution for forming a fluoropolymer coating comprising:i) an organic solvent, and dissolved therein (a) fluoroolefin selected from the group consisting of tetrafluoroethylene, chlorotrifluoroethylene, hexafluoropropylene, perfluoro(methyl vinyl ether), perfluoro(ethyl vinyl ether), and perfluoro(propyl vinyl ether);', '(b) alkyl vinyl ether wherein the alkyl group is a C1 to C6 straight chain saturated hydrocarbon radical or a C3 to C6 branched chain or cyclic saturated hydrocarbon radical, or aryl vinyl ether wherein the aryl group is unsubstituted or substituted; and', '(c) alkenyl silane of the formula SiR1R2R3R4, wherein R1 is an ethylenically unsaturated hydrocarbon radical, R2 is aryl, aryl substituted hydrocarbon radical, branched C3-C6 alkoxy radical, or substituted or unsubstituted cyclic C5-C6 alkoxy radical, and R3 and R4 are independently selected from linear or branched C1-C6 alkoxy radical, or substituted or unsubstituted cyclic C5-C6 alkoxy radical., 'ii) a fluoropolymer comprising repeat units arising from monomers2. The solution of claim 1 , wherein said solvent is a ketone claim 1 , glycol ether or halocarbon having a ...

Принадлежит: WL Gore and Associates Inc

A functional TFE copolymer fine powder is described, wherein the TFE copolymer is a polymer of TFE and at least one functional comonomer, and wherein the TFE copolymer has functional groups that are pendant to the polymer chain. The functional TFE copolymer fine powder resin is paste extrudable and expandable. Methods for making the functional TFE copolymer are also described. The expanded functional TFE copolymer material may be post-reacted after expansion.
