Zusammenfassung:	Compositions may be reacted partially to a thermoplastic, elastomeric intermediate stage (B-stage) having excellent shelf stability at room temperature. The thermoplastic (B-stage) compositions may be heated to cure to a thermoset, elastomeric, tack-free final stage (C-stage). The compositions comprise (A) 1 equivalent weight of at least one cycloaliphatic epoxy resin, (B) from about 0.05 to about 0.5 equivalent weight of at least one amine-terminated liquid polymer having a carbon-carbon backbone and (C) from about 0.4 to about 1.5 equivalent weight of at least one anhydride. The compositions are useful as solventless adhesives (alone or compounded with rubber stock or the like) for conveyor belts, hoses, shoes, iron-on clothing patches, and the like. The compositions are also useful as paints, powder coatings, binders for woven or non-woven fibers and cords, and the like.
