Abstract: Crosslinkable compositions, crosslinked compositions, articles containing these compositions, and methods of making the articles are provided. The crosslinkable compositions, which include two (meth)acrylate polymers, are used to form the crosslinked compositions upon exposure to ultraviolet radiation. The crosslinkable and crosslinked compositions are free or substantially free of tackifiers. The crosslinked compositions can function as pressure-sensitive adhesives. The crosslinkable compositions are well suited for use with hot melt processing methods.

Abstract: Methods and apparatuses for applying liquid coatings are provided. A first roll (14), a second roll (16), and a nip (146) formed between the first and second rolls are provided. A coating liquid (22) is supplied to the nip. The coating liquid is smoothed, via the nip, into a substantially uniform layer (22a) of liquid coating which is transferred to a substrate (12). The second roll (16) includes a thin metal shell (40) and a resilient layer (30), the thin metal shell encases the resilient layer therebeneath, and the thin metal shell is capable of deflecting in unison with the resilient layer such that the thin metal shell is elastically deformable at the nip when in contact with the first roll (14).

Abstract: Stretch-release adhesives are provided which are derived from mixtures comprising: a) a tackified styrenic block copolymer comprising: i) one or more tackifiers; and ii) one or more styrenic block copolymers; wherein the weight ratio of i) to ii) is not more than 1.0:2.0; and b) one or more (meth)acrylate polymers. In some embodiments, the weight ratio of a) to b) is between 0.4:1.0 and 5.0:1.0 and in some between 1.0:1.0 and 3.9:1.0. In some embodiments, the one or more styrenic block copolymers comprise at least 90 wt % linear block copolymers. In some embodiments, the tackifiers are miscible with rubbery blocks of the styrenic block copolymers and not miscible with the (meth)acrylate polymers. In some embodiments, the mixture is crosslinked. Tapes comprising stretch-release adhesives according to the present disclosure are also provided.
