Disclosed is a method of making an adhesive comprising forming a first composition of a polyesterether glycol having the general formula <IMAGE> where R1 and R2 are each independently selected from alkylidene from C1 to C10, and n is about 1 to about 5 about 0.01 to about 1% by weight (based on the weight of the polyesterether glycol) of a catalyst, and sufficient solvent for said adhesive to have at least 50% solids, forming a second composition of about 0.85 to about 0.95 mole % of a diisocyanate and about 0.15 to about 0.05 mole % of a polyisocyanate, and mixing the first and second compositions together. The adhesive is applied to a first substrate, the solvent is evaporated, and a second substrate is pressed against the adhesive on the first substrate to form a flexible laminate.
