Abstract: A method is provided for bonding substrates using a prepolymer composition that is cured with electron beam radiation. The prepolymer composition provided for bonding the substrates contains at least one polyester resin and at least one polymerizable compound.

Abstract: A one-liquid cold setting adhesive comprising a thermoplastic, non-reactive polyurethane polymer dissolved in an addition-polymerizable combination of an acrylic or methacrylic monomer other than the acids, a copolymerizable monomer containing at least one free carboxylic group, a non-activated free radical addition polymerization catalyst system and an activator for the free radical catalyst system encapsulated in pressure-rupturable microspheres or beads having a composition which is substantially insoluble in the presence of the other components of the mixture for a relatively long time period. Exemplary of this adhesive formulation is a polyester polyurethane containing no free isocyanate groups dissolved in a mixture of methacrylic acid and methyl methacrylate, each of the three components being present in equal amounts. Included in the mix is benzoyl peroxide and hydroquinone.
