    Abstract: Release liners that can be included in various adhesive products are provided. A first release liner is a layer of a composition including a) a polymeric material having at least one hydrogen atom covalently bonded to an oxygen atom, a nitrogen atom, or a sulfur atom; and b) a silicone polyether comprising at least one of polyoxoethylene units or polyoxopropylene units. A second release liner includes a substrate and a coating of the above composition disposed on a major surface of the substrate. The present disclosure also provides an article including one of the above release liners and an adhesive layer disposed on a major surface of the release liner. The composition of the release liner can advantageously be dissolved and optionally recycled.

    Abstract: A method of making an adhesive article includes providing a liner having first and second silicone release layer disposed on opposite sides thereof, applying the onium salt photoacid generator onto at least a portion of the first silicone release layer to provide a modified silicone release layer, disposing an adhesive layer onto the second silicone release layer, and and exposing at least the adhesive layer to electron beam radiation within a process chamber thereby providing a crosslinked adhesive layer, wherein the process chamber contains oxygen, wherein the modified silicone release layer is exposed to the oxygen during crosslinking of the adhesive layer. The first silicone release layer does not contain an onium salt photoacid generator. An adhesive article made by the method is also disclosed.

    Abstract: A method of making an adhesive article comprises three steps. First, a backing is provided having first and second opposed major surfaces with respective first and second silicone release layers disposed thereon. The second silicone release layer further comprises organic solvent and a compound represented by the formula: R1 represents a monovalent, divalent, or trivalent hydrocarbon radical having from 2 to 40 carbon atoms or covalent bond. Rf represents a perfluorinated group having from 3 to 5 carbon atoms. X1 represents —NH— or a covalent bond. Second, an adhesive layer is disposed onto the first silicone release layer. Third, the adhesive layer is exposed to E-beam radiation within a process chamber containing oxygen to provide a crosslinked adhesive layer. An adhesive article made by the method and the compound are also disclosed.
