Abstract: The present application relates to polyurethane polymers produced by polymerizing a reactant mixture comprising triglycerides of Physaria fendleri, one or more polyisocyanates, and one or more polyols, wherein the triglycerides of Physaria fendleri have a hydroxyl value ranging from 90 milligrams of potassium hydroxide per gram of the triglycerides of Physaria fendleri to 250 milligrams of potassium hydroxide per gram of the triglycerides of Physaria fendleri. The present application also relates to polyester polymers produced by polymerizing a reactant mixture comprising triglycerides of Euphorbia Lagascae, and one or more dicarboxylic acids. Also disclosed are the methods of formation of the polyurethane and polyester polymers, and their use as adhesives.
