Looking beyond the traditional applications of polyurethanes (PUR), Polyurethanes as Specialty Chemicals presents a different approach to polyurethane chemistry by examining a range of new products and new research for both environmental and medical applications. This book is also the first in its field to provide useful design tools for product designers to customize the foam surface. The author examines extraction methods and biodegradability of polyurethanes for removing pollutants from air and groundwater and for sanitation/wastewater treatment. Thomson also explores the behavior of polyurethanes in a biological environment, covering a broad spectrum of applications that includes artificial organs, chelating agents for pharmaceuticals, and delivery systems for skin care products and cosmetics. The in-depth treatment of biochemical processes and cellular interaction includes tissue response, cell adhesion, 3D cell scaffolding for cell propagation, the immobilization of enzymes, and the production of proteins. Other topics of interest include agricultural applications and the use of PUR as an analytical/diagnostic system for testing toxicity without the use of animals. Destined to become indispensable in its field, Polyurethanes as Specialty Chemicals explores conventional PUR and its composites - emphasizing formulations, reticulated foams and hydrophilics - as versatile structures that can be used for specific design objectives in environmental and medical applications.

A practical handbook rather than merely a chemistry reference, Szycher's Handbook of Polyurethanes, Second Edition offers an easy-to-follow compilation of crucial new information on polyurethane technology, which is irreplaceable in a wide range of applications. This new edition of a bestseller is an invaluable reference for technologists, marketers, suppliers, and academicians who require cutting-edge, commercially valuable data on the most advanced uses for polyurethane, one of the most important and complex specialty polymers. internationally recognized expert Dr. Michael Szycher updates his bestselling industry "bible" With seven entirely new chapters and five that are revised and updated, this book summarizes vital contents from U.S. patent literature—one of the most comprehensive sources of up-to-date technical information. These patents illustrate the most useful technology discovered by corporations, universities, and independent inventors. Because of the wealth of information they contain, this handbook features many full-text patents, which are carefully selected to best illustrate the complex principles involved in polyurethane chemistry and technology. Features of this landmark reference include: Hundreds of practical formulations Discussion of the polyurethane history, key terms, and commercial importance An in-depth survey of patent literature Useful stoichiometric calculations The latest "green" chemistry applications A complete assessment of medical-grade polyurethane technology Not biased toward any one supplier’s expertise, this special reference uses a simplified language and layout and provides extensive study questions after each chapter. It presents rich technical and historical descriptions of all major polyurethanes and updated sections on medical and biological applications. These features help readers better understand developmental, chemical, application, and commercial aspects of the subject.

One way of improving performance attributes of building structures is to use a new class of materials—polymer composites. They have unique properties that combine high strength with features of non-metallic materials. Polymer concretes (PC) appear to offer many possibilities for producing new materials with desired physical and mechanical characteristics, such as improved mechanical strength, low permeability, and greater chemical resistance. Advanced Polymer Concretes and Compounds presents the results of theoretical and experimental research on efficient building material composites based on advanced polymer binders. This book examines the composition and properties of two new polymer concretes that have potential to solve various construction issues: rubber concrete based on a polybutadiene binder and silicate polymer concrete with an organo-silicate matrix. It examines the physical, mechanical, and technological properties of these PCs as well as their behavior in harsh environments and durability and reliability issues. The authors describe a new environmentally friendly polymer for monolithic industrial floor coverings and coatings—nonisocyanate polyurethanes. They also discuss advanced crack-resistant coatings based on water dispersion of chlorosulfonated polyethylene, which can be used on concrete, metal, and plastic for various industrial uses such as aircraft, automobiles, paint, and in shipbuilding and civil engineering. The book covers a new type of epoxy composition with nano-heterogenic structure with potential for better mechanical properties and chemical resistance, acid-resistant building materials based on a nanostructured binder, and an advanced environmentally friendly and weather-resistant fire-protective coating for indoor and outdoor application to flammable substrates. With a focus on novel concretes and protective compounds for a variety of environments, this book reflects the newest developments in the rapidly growing field of building materials engineering.

These contribution books collect reviews and original articles from eminent experts working in the interdisciplinary arena of biomaterial development and use. From their direct and recent experience, the readers can achieve a wide vision on the new and ongoing potentialities of different synthetic and engineered biomaterials. Contributions were selected not based on a direct market or clinical interest, but on results coming from a very fundamental studies. This too will allow to gain a more general view of what and how the various biomaterials can do and work for, along with the methodologies necessary to design, develop and characterize them, without the restrictions necessary imposed by industrial or profit concerns. Biomaterial constructs and supramolecular assemblies have been studied, for example, as drug and protein carriers, tissue scaffolds, or to manage the interactions between artificial devices and the body. In this volume of the biomaterial series have been gathered in particular reviews and papers focusing on the application of new and known macromolecular compounds to nanotechnology and nanomedicine, along with their chemical and mechanical engineering aimed to fit specific biomedical purposes.
