    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.

    Abstract: Described herein is a functionalized oligomeric compound, which can be polymerized into a peroxide curable highly fluorinated polymer. The functionalized oligomeric compound is at least one of a monofunctional compound of formula (I) R-L-X having a number average molecular weight of 1000-16,000 g/mol; or a difunctional compound of formula (II) is R1-(L-X1)2 having a number average molecular weight of 1000-6000 g/mol; where: X comprises at least one of: —CH═CH2, —CH2CH═CH2, —OCH═CH2, —OCH2CH═CH2, —OCH2C(CH3)═CH2, —C(CH3)═CH2, and —OCF═CF2; X1 comprises at least one of: —CH═CH2, —CH2CH═CH2, —OCH═CH2, —OCH2CH═CH2, —OCH2C(CH3)═CH2, and —C(CH3)═CH2; L comprises at least one of a bond, —CH2OC(═O)—, —CH2OC(═O)NHCH2CH2OC(═O)—, and —C(═O)NHCH2CH2OC(═O)—; R is a monovalent perfluoro polyether alkyl group; and R1 is a divalent perfluoro polyether alkylene group. Such functionalized oligomeric compounds may be used as improve the processability of highly fluorinated polymers and may improve the physical properties of the resulting cured fluoropolymer.
