Abstract: Adhesive articles include a substrate; and a hot melt processable pressure sensitive adhesive on the substrate. The hot melt processable pressure sensitive adhesive is a (meth)acrylate-based copolymer that is the reaction product of a reaction mixture that is free of acidic or basic monomers, and includes an alkyl (meth)acrylate, a hydroxyl-functional (meth)acrylate, and a photocrosslinker. The (meth)acrylate-based polymer is prepared in a thermoplastic package.

Abstract: Medical articles include a substrate with a layer of a siloxane-based gel adhesive composition. The gel adhesive composition includes a crosslinked polymeric siloxane matrix, and an extractable polymeric fluid with a weight average molecular weight greater than 275,000 grams/mole. The extractable polymeric fluid is 26-80 weight % of the gel adhesive composition. The gel adhesive composition may also include a siloxane tackifying resin.
