Abstract: Electronic telecommunication articles are described comprising a crosslinked fluoropolymer layer. In typical embodiments, the crosslinked fluoropolymer layer is a substrate, patterned (e.g. photoresist) layer, insulating layer, passivation layer, cladding, protective layer, or a combination thereof. Also describes are methods of making an electronic telecommunications article and method of forming a patterned fluoropolymer layer. The fluoropolymer preferably comprises at least 80, 85, or 90% by weight of polymerized units of perfluorinated monomers and cure sites selected from nitrile, iodine, bromine, and chlorine. Illustrative electronic communication articles include integrated circuits, printed circuit boards, antennas, and optical fiber cables. Fluoropolymer compositions are also described.

Abstract: Compositions are described comprising at least one fluoropolymer, a solvent and an amino compound. The fluoropolymer comprises at least 90% by weight based on the total weight of the fluoropolymer of polymerized units derived from perfluorinated monomers selected from tetrafluoroethene (TFE) and one or more unsaturated perfluorinated alkyl ethers. The fluoropolymer typically comprises one or more cure sites, such as nitrile or halogenated cure sites. The solvent typically comprises a branched, partially fluorinated ether. In preferred embodiments the amine compound further comprises a silane group. Also described are methods of making the coating composition, methods of coating a substrate with UV and/or thermal curing, and the coated substrate.

Abstract: A method of making a crosslinked fluoropolymer is described. The method comprises applying a composition to a substrate, wherein the composition comprises fluoropolymer and a fluorinated solvent, one or more curing agents comprising an ethylenically unsaturated group and an electron donor group or precursor thereof. The method further comprises removing the solvent and curing the fluoropolymer with actinic (e.g. ultraviolet “UV”) radiation. Also described is a composition comprising a fluoropolymer dissolved in a fluorinated solvent, and one or more curing agents comprising an ethylenically unsaturated group and an electron donor group or precursor thereof; and article comprising the crosslinked fluoropolymer.
