This invention relates to a novel curing method of oligomers, using metal triflates, and particularly to the curing of hydroxyl terminated elastomers to achieve crosslinked polymers. The method finds particular use as an alternative cure methodology to replace isocyanate curing. There is further provided a cured and crosslinked polymer binder, which is particularly suitable and compatible for use with energetic materials.

An adhesive formulation having an adduct of an epoxy resin and an elastomer, a phenoxy epoxy hybrid resin supplied as a solution formed by dissolving a phenoxy resin in a liquid epoxy resin to form a pre-formed dissolution product, a core/shell polymer, and one or more additional epoxy resins. The adhesive formulation may include a curing agent, blowing agent, filler, accelerator, or a combination.
