Abstract: Described are adhesive compositions containing a block copolymer component that includes a midblock segment and a plurality of end block segments, each end block segment comprising polystyrene, a (meth)acrylic functional additive having a glass transition temperature of from 50° C. to 160° C., a first tackifier compatible with the midblock segment and containing a hydrocarbon, and a second tackifier compatible with the end block segments and containing a polyphenylene ether. These compositions are useful in providing pressure-sensitive adhesives that are melt processible, display a high temperature resistance, and effectively bond to low surface energy substrates.

Abstract: Pressure-sensitive adhesive compositions and articles that include a layer of the pressure-sensitive adhesive compositions are provided. The pressure-sensitive adhesive compositions are particularly well suited for use with substrates that have been considered to have difficult to bond to surfaces such as those routinely encountered in the automotive industry. For example, the pressure-sensitive adhesive can be adhered to clear coat compositions, painted surfaces, and various polymeric materials having low energy surfaces (e.g., surfaces having a surface energy no greater than 35 dynes per centimeter).

Abstract: A core-sheath filament including a crosslinkable adhesive core that can be cured using ultraviolet or visible light radiation. These crosslinkable adhesive core compositions can provide very high bond strength and are capable of replacing traditional mechanical fasteners in many industrial applications. Core-sheath filaments including such crosslinkable compositions, crosslinked compositions, articles containing these compositions, and methods of making the articles are provided. The crosslinkable compositions contain pendant aromatic ketone groups or pendant (meth)acryloyl groups that, upon exposure to ultraviolet radiation, result in the formation of crosslinks within the polymeric material. The crosslinked compositions can function as pressure-sensitive adhesives.
