    Abstract: Three-dimensional polymeric article (100) having first (101) and second (102) opposed major surfaces, a base body (103) having a first dimension, a second dimension perpendicular to the first dimension, and a thickness, wherein the thickness is orthogonal to the first and second dimensions, wherein the base body (103) comprises a plurality of alternating, adjacent first (107) and second (108) polymeric regions along the first dimension, wherein the second dimensions of the first (107) and second (108) regions extend at least partially across the second dimensions, wherein the first regions (107) have a first crosslink density, wherein the second regions (108) have a second crosslink density, wherein the second crosslink density of the second regions (108) are less than the first crosslink density of the first regions (107), wherein the first and second regions extend perpendicularly in two directions from a central plane (115) in the base body (103) parallel to the first and second dimensions of the polymeric article (100), and wherein the second regions (108) extend in each of said two directions further than does the first regions (107). Embodiments of the three-dimensional polymeric article described herein are useful for providing a dual sided, textured wrapping film such that greater grip is realized both on an item wrapped by the film and the wrapped item itself.

    Abstract: Adhesive compositions and methods of preparing an adhesive composition are described. The method comprises providing a syrup composition comprising a free-radically polymerizable solvent monomer and a solute (meth)acrylic copolymer, and radiation curing the syrup composition in the absence of an ionic photoacid generator. The solute (meth)acrylic copolymer comprises epoxy-functional groups, acid-functional groups, or a combination thereof. In some embodiments, an epoxy resin having on average greater than one polymerizable epoxy group per molecule or an acid comprising at least two carboxylic acid groups is utilized. The epoxy-functional groups and acid-functional groups of the (meth)acrylic copolymer or the adhesive composition can readily crosslink in the absence of an ionic photoacid generator (PAG).

    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.
