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.
