Abstract: Adhesive articles with multi-layer adhesive constructions include a substrate and a multi-layered adhesive. The multi-layered adhesive includes a layer of a first adhesive in contact with the surface of the substrate, and a layer of siloxane-based pressure sensitive adhesive in contact with the first adhesive. The siloxane-based pressure sensitive adhesive includes a siloxane-(meth)acrylate co-polymer. The thickness of the siloxane-based pressure sensitive adhesive layer is less than the thickness of the first adhesive layer.

Abstract: Curable precursor compositions for adhesives (e.g., pressure sensitive adhesives) and related articles, assemblies, and methods. The provided compositions contain a mixture comprising 50 to 100 parts by weight of a first polymerizable component, 0 to 50 parts by weight of a second polymerizable component, a transition metal complex soluble in the mixture, and an effective amount of a polymerization initiator, thereby allowing for the formation of high molecular weight polymer with essentially no gel content that can be easily processed via established hot melt techniques (i.e., a hot melt processable adhesive), even in the absence of chain transfer agents or crosslinking agents.
