  A modified polyurethane adhesive composition characterized by its improved viscosity and high initial bond strength contains an isocyanate-terminated prepolymer or a fully reacted polyurethane and a monomeric carbamate ester which is compatible and not reactive with the prepolymer or polyurethane. The resultant adhesive is suitable for laminating many types of substrates. In a preferred embodiment the prepolymer is employed with the carbamate ester in a reactive hot-melt adhesive for use in bonding flexible substrates.

  The addition to urethane prepolymers of low molecular weight polymers formed from ethylenically unsaturated monomers which do not contain active hydrogen provides a hot melt adhesive which can be readily coated at a viscosity of 3000 to 50,000 cps. at 120°C without the need for additinal tackifiers or plasticizers and which has improved initial cohesive strength as well as improved strength after aging of the cured bond. In a preferred embodiment of the invention, the ethylenically unsatured monomers are polymerized in the non-isocyanate containing components of the isocyanate terminated prepolymer.
