• Resumen

  • Thermosetting polymers are made from a mixture of monomers which react to form a large macromolecular network. They are used in diverse fields such as aerospace technology and wood composites, mostly as adhesives. The history of these products can be traced to ancient Egypt. The main thermosetting systems used nowadays are phenol-formaldehyde, urea-formaldehyde, polyurethanes polyesters and epoxydes. Each of these is reviewed briefly as to its chemistry and applications. The physical chemistry of these adhesives can be followed by differential scanning calorimetry and rheometry and examples are given.
