01 Polyurethane The structure of polyurethane is formed by the reaction of polyisocyanates (e.g., diisocyanate OCN-R-NCO) and polyols (e.g., diol HO-R-OH), where urethane segments are repeating structural units. Polyurethane structures have structures similar to amide and ester groups; therefore, the chemical and physical properties of polyurethane are between those of polyamides and polyesters. S...
