This book, cohesively written by an expert author with supreme breadth and depth of perspective on polyurethanes, provides a comprehensive overview of all aspects of the science and technology on one of the most commonly produced plastics.
* Covers the applications, manufacture, and markets for polyurethanes, and discusses analytical methods, reaction mechanisms, morphology, and synthetic routes
* Provides an up-to-date view of the current markets and trend analysis based on patent activity and updates chapters to include new research
* Includes two new chapters on PU recycling and PU hybrids, covering the opportunities and challenges in both
