Ethynyl-containing phenoxy resins have excellent shelf life in solution or in bulk. Cured ethynyl-containing phenoxy resins offer lower moisture absorption, higher use temperatures, and better thermal stability over stateof-the-art cross-linked phenoxy resins. Depending upon cross-link density, cured ethynyl-modified phenoxy resins are solvent resistant but still thermoformable and relatively tough. Modified resins show potential for use as adhesives, composite matrices, solvent-resistant coatings, membranes, insulators, and films.
