Abstract: Curable compositions, cured compositions, articles containing the curable or cured compositions, and methods of making the articles are provided. More particularly, the curable compositions contain a (meth)acrylate-based polymer having pendant (meth)acryloyl groups, at least one monomer having a single ethylenically unsaturated group, a photoinitiator that includes an acyl phosphine oxide, and a thixotropic agent. The curable compositions can be printed or dispensed, if desired, and the cured compositions are pressure-sensitive adhesives.

Abstract: A crosslinkable composition, a crosslinked composition formed upon exposure of the crosslinkable composition to ultraviolet radiation or ionizing radiation, articles containing these compositions, and methods of making the articles are described. The crosslinkable compositions contain two different (meth)acrylate copolymers and can be applied to a substrate using an extrusion process. While being extruded, the crosslinkable compositions advantageously are resistant to crosslinking and/or increased molecular weights. The crosslinked compositions can function as adhesive compositions that are particularly well suited for use in electronic devices.

Abstract: A crosslinkable composition, a crosslinked composition formed upon exposure of the crosslinkable composition to ultraviolet radiation or ionizing radiation, articles containing these crosslinkable or crosslinked compositions, and methods of making the articles are described. The crosslinkable compositions contain two different (meth)acrylate polymers and can be applied to a substrate using an extrusion process. While being extruded, the crosslinkable compositions advantageously are resistant to crosslinking and/or significantly increasing in molecular weight. The crosslinked compositions can function as either a pressure-sensitive adhesive composition or a heat bondable adhesive composition and are particularly well suited for use in electronic devices.
