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: Described herein is curable composition comprising a halogenated amorphous polymer having at least 25% halogen by weight; at least 0.5 phr of an acid acceptor; at least 0.01 phr of silicon-containing compound; and a dehydrohalogenation cure system. Upon curing, a silicon-containing superficial layer forms, which can provide increased durability, non-tackiness, and a matte finish to the cured elastomer.

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.

Abstract: Methods of bonding highly-fluorinated thermoplastics to elastomers are described. The methods include apply primers comprising at least one aromatic silane and at least one amino-silane to an uncured elastomer and irradiating the primer with actinic radiation before or after applying the highly-fluorinated thermoplastics. The elastomer may then be cured to provide articles having good adhesion between the highly-fluorinated thermoplastic and the cured elastomer.
