Abstract: Electronic telecommunication articles are described comprising a layer of fluoropolymer composition comprising: an amorphous fluoropolymer comprising at least 80, 85, or 90% by weight of polymerized units perfluorinated monomers including one or more unsaturated perfluorinated alkyl ethers; and crystalline fluoropolymer; wherein the fluoropolymer composition lacks crosslinks of a chemical curing agent. Also described are methods of making a coated substrate, substrates comprising a fluoropolymer composition, and fluoropolymer compositions.

Abstract: An electronic telecommunication article is described comprising a layer of fluoropolymer composition comprising an uncrosslinked fluoropolymer comprising at least 80, 85, or 90% by weight of polymerized units perfluorinated monomers including one or more unsaturated perfluorinated alkyl ethers. In typical embodiments, the uncrosslinked fluoropolymer comprises at least 10, 20, or 30 wt. % of one or more unsaturated perfluorinated alkyl ethers. The uncrosslinked fluoropolymer may be characterized as amorphous. The uncrosslinked fluoropolymer is soluble in fluorinated solvent. Also described are coated (e.g. copper) substrates, methods, and compositions.

Abstract: Electronic telecommunication articles are described comprising a layer of fluoropolymer composition comprising a fluoropolymer or fluoropolymer blend comprising at least 1 wt. % and less than 30 wt. % of polymerized units of unsaturated (per)fluorinated alkyl ether(s). Also described are methods of making a coated substrate, a substrate comprising a fluoropolymer composition, and fluoropolymer compositions.

Abstract: A method of bonding a substrate is described comprising providing a fluoropolymer film comprising: i) a first fluoropolymer comprising at least 80, 85, or 90 wt. % of polymerized perfluorinated monomers; ii) optionally a second fluoropolymer having a greater amount of polymerized tetrafluoroethylene than the first fluoropolymer; wherein the first fluoropolymer and/or second fluoropolymer when present comprises halogen cure sites; and iii) one or more compounds comprising an electron donor group and one or more ethylenically unsaturated groups; applying the fluoropolymer film to a substrate; and heating the fluoropolymer film to a temperature of at least 150, 160, 170, 180, 190 or 200° C.
