Abstract: The use of a monomer as the solvent in both components of a urethane polymerization system eliminates the need for the expenditure of much energy to remove solvent from the cured resin. The exotherm of the urethane cure supplies the heat for the activation of a relatively thermally stable free radical catalyst which then catalyzes the curing of the monomer. The two component system is stable in storage.

Abstract: Pressure-sensitive adhesive composition is disclosed wherein the adhesive is a 100 % solids, no solvent, tacky oil that can cure at ambient conditions. The adhesive comprises an acrylic oligomer component and a polyurethane prepolymer in combination. The oligomer comprises repeat units, corresponding to acrylic acid, lower alkyl acrylate and hydroxylated lower alkyl acrylate monomers. The prepolymer is formed via polyisocyanate reaction with a multifunctional active hydrogen containing compound, such as a polyol.
