ABSTRACT
Polyurethanes enjoy outstanding versatility in their range of monomers, polymerization reactions, processing, structures, properties, and applications. This versatility has contributed greatly to our understanding of polymer structure-property relations in general and to the production of high-performance elastomers, plastics, fibers, foams, coatings, and adhesives. Structure-property relations are best analyzed stepwise from the smallest submolecular structural features, up through molecular weight and flexibility, intermolecular order and bonding, and supermolecular structural features.
