Abstract: Described herein is curable composition comprising a partially halogenated elastomeric gum comprising a plurality of cure sites selected from at least one of iodine, bromine, and nitrile; a silicon-containing compound; a dehydrohalogenation agent; and a peroxide cure system. Upon curing, a silicon-containing superficial layer forms, which can provide good chemical stability, increased durability, non-tackiness, and a matte finish to the cured elastomer.

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: The composition can include a fluoropolymer and a branched silsesquioxane polymer having terminal —Si(R3)3 groups and units having formula, in which * represents a bond to another silicon atom in the branched silsesquioxane polymer, R is an organic group comprising an aliphatic carbon-carbon double bond, and R3 is a non-hydrolyzable group or hydrogen. The fluoropolymer can be crosslinked with the branched silsesquioxane polymer. An article can include a first composition including a fluoropolymer in contact with a second composition including a silicone, wherein at least one of the first composition or second composition includes the branched silsesquioxane polymer. At least one of the fluoropolymer or the silicone can be crosslinked with a branched silsesquioxane polymer including terminal —Si(R3)3 groups and units having formula, in which R* is an organic group comprising a carbon-carbon bond between the branched silsesquioxane polymer and the fluoropolymer, the silicone, or another R* group.
