This book provides a thorough presentation of polyurethane (PU) science, technology, markets and trends.? Although it does not provide ultimate detail (such as explicit information typically in patents), the book has a flow and continuity that allows readers to find all the background necessary to understand any other more detailed PU information found elsewhere. The author presents chapters about PU chemistry, characteristics, analytical methods, theoretical methods, and a host of applications examples: foams, elastomers, coatings, adhesives, and medical. Additionally, there is discussion of medical applications and non-isocyanate/non-phosgene ?routes to urethane structure. Governmental regulation of polyurethane reagents and? building blocks is covered in detail, as well industrial means of mitigating risks.
