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: Acrylic pressure-sensitive adhesive ("PSA") compositions crosslinked with a small-molecule crosslinker containing a single, thermally reversible moiety represented by the structure (I) (Formula I) ). wherein each R1 is independently -H or -CH3, each X is independently C2-C6 alkyl, and each R2 is independently a C1-C6 alkyl group or an aromatic group. Under high temperature conditions the crosslinks may be broken, thus allowing for good coating and dispensing of the PSA. Upon cooling, the crosslinks reform to create a gelled PSA network without need of additional post-processing curing steps.

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.
