Polyester-epoxide polymer (PEEP) compositions are disclosed. The PEEP compositions comprise a reaction product of a polyepoxide compound (eq. wt. 125 to 250 g/eq.) and a polyester polyol composition. The ratio of epoxy equivalents to hydroxyl equivalents is within the range of 0.8 to 3.5. The PEEP composition has a Tg within the range of −40° C. to 60° C. Elevated temperature-cure and low temperature-cure processes for making the PEEP compositions are also disclosed. In a simple yet innovative approach, a new class of polymers useful for adhesives, coatings, elastomers, and other valuable products is assembled from readily available starting materials without reliance on polyisocyanates or polyamines. The PEEP compositions have increased elongation and lower Tg when compared with traditional epoxy products.
