This volume describes in detail the mechanisms of the diisocyanates and polyols polyaddition process as well as its kinetic and process aspects important for obtaining linear polyurethanes. General kinetics of the process and its experimental verification, using GPC chromatography as well as NMR spectroscopy and MALDI-ToF spectrometry, are presented. Accompanied by over 400 references, the author presents synthesis methods, physicochemical properties of linear polyurethanes (analyzed with DCS, TG, DMTA, Rtg, AFM microscopy methods) as semiproducts for foams, elastomers, lacquers and coatings. Research results concerning free surface energy of the polyurethane coatings are also presented. Special attention is given to the latest polyurethane applications, such as ecological waterborne dispersions, biodegradation resistant elastomers and coatings used as medical implants and binders for ceramic powder materials. Moreover, the book contains information on urethane-isocyanate prepolymers applications, which are potential semifinished products for elastomers, foams, coatings, adhesives and interpenetrating polymer network composites.

Polyurethanes are formed by reacting a polyol (an alcohol with more than two reactive hydroxyl groups per molecule) with a diisocyanate or a polymeric isocyanate in the presence of suitable catalysts and additives. Because a variety of diisocyanates and a wide range of polyols can be used to produce polyurethane, a broad spectrum of materials can be produced to meet the needs of specific applications. During World War II, a widespread use of polyurethanes was first seen, when they were used as a replacement for rubber, which at that time was expensive and hard to obtain. During the war, other applications were developed, largely involving coatings of different kinds, from airplane finishes to resistant clothing. Subsequent decades saw many further developments and today we are surrounded by polyurethane applications in every aspect of our everyday lives. While polyurethane is a product that most people are not overly familiar with, as it is generally "hidden" behind covers or surfaces made of other materials, it would be hard to imagine life without polyurethanes.

This book is a collection of 22 per-reviewed scientific papers on the synthesis and characterization of polyurethanes with special chemical and physical properties. In our "plastic age", polyurethanes are one of the most versatile polymers with broad and excellent mechanical and chemical properties. These polyurethanes can be found in many areas of our every day`s life ranging from insulators through hard and soft foams to various biomedical devices. The huge number of possible variations in the types of reactants allows the scientists to design and tailor the properties of polyurethanes to specific needs. The fascinating chemistry and materials science of polyurethanes have attracted interests of many scientists. As a result, the progress in this field made by these scholars are summarized in this book with special emphasizes on the structure-property relationships and biomedical applications of polyurethanes as well as their environmental aspects are also highlighted in some papers. Thus, this collection of papers is recommended to all readers who are interested not only in the synthesis and properties of polyurethanes but want to be familiar with the theoretical description of their formation as well.

This successful textbook undergoes a change of character in the third edition. Where earlier editions covered organic polymer chemistry, the third edition covers both physical and organic chemistry. Thus kinetics and thermodynamics of polymerization reactions are discussed. This edition is also distinct from all other polymer textbooks because of its coverage of such currently hot topics as photonic polymers, electricity conducting polymers, polymeric materials for immobilization of reagents and drug release, organic solar cells, organic light emitting diodes. This textbook contains review questions at the end of every chapter, references for further reading, and numerous examples of commercially important processes.
