Abstract: An article comprising a first component having a first electrically conductive surface and a second component having a second surface. An adhesive composition comprising a cured polymerizable ionic liquid is disposed between the first electrically conductive surface and second surface and joins the first component to the second component. The polymerizable ionic liquid comprises an acid functional monomer and the conjugate acid of an imidazole compound. The effort required to separate the first component from the second component, as measured by work of adhesion per surface area, is reduced by application of a DC electric potential across the adhesive composition.

Abstract: A method of preparation of olefin-functionalized fluorosilicones, the properties of which can be optimized, for example, as release liners for silicone adhesives, the method including subjecting a mixture of a hydride-functional polysiloxane, a first compound having a terminal monosubstituted olefin, and a second compound having both a terminal monosubstituted olefin and an internal disubstituted olefin to hydrosilylation conditions to provide a hydrosilylated fluorosilicone with internal olefins and reacting the hydrosilylated fluorosilicone with internal olefins with ethylene in the presence of an olefin metathesis catalyst to provide the olefin- functionalized fluorosilicone. Articles including such olefin-functionalized fluorosilicones.
