Abstract: A perfluoropolyether thiol compound comprises a perfluoropolyether segment, at least one mercapto group (—SH), and at least one intervening divalent carbonylimino moiety (—C(═O)—NR—, wherein R is hydrogen or alkyl). The compound can be produced, for example, by a ring-opening reaction of thiolactones with perfluoropolyether-substituted, primary or secondary amines. The compound can be used, for example, as a polymerization chain transfer agent, as an intermediate for the preparation of functional group-containing fluorochemical derivatives such as disulfides, and as a fluorinated surface treatment.

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.
