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.

Shape memory materials are immensely useful because of their capability to recover their original shapes upon exposure to an external stimulus such as heat, moisture, light or a magnetic field. This book reviews key recent research in shape memory polymers, their properties and applications. Topics include the relationship between morphological structures and shape memory properties; high performance Tg and Tm type shape memory polymers; structures of shape memory polymers with supramolecular switches; and the thermally-active and moisture-active shape memory effect of supermolecular shape memory polymers. Advances in shape memory polymers is an essential reference for polymer and textile material students, scientists, designers, engineers and manufacturers. It is also an invaluable guide for professionals in the biomedical, electronics and engineering industries.
