<p>The invention relates to polymer compositions suitable for use in coating applications or as adhesives. The compositions comprise at least two compatible, solidifiable, liquid oligomers and are spreadable at ambient temperature, do not involve conventional solvents and can attain a finite intermediate stage at which they are tacky and have cohesive strength. Typical examples of such compositions are (a) two different end group-tipped butadiene/acrylonitrile copolymers, and (b) two different types of isocyanate-terminated urethane prepolymers.</p> |
