Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Aspects of Polyurethanes written by Faris Yılmaz and published by BoD – Books on Demand. This book was released on 2017-09-27 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Interpenetrating Polymer Networks and Related Materials written by L.H. Sperling and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 269 pages. Available in PDF, EPUB and Kindle. Book excerpt: To the surprise of practically no one, research and engineering on multi polymer materials has steadily increased through the 1960s and 1970s. More and more people are remarking that we are running out of new monomers to polymerize, and that the improved polymers of the future will depend heavily on synergistic combinations of existing materials. In the era of the mid-1960s, three distinct multipolymer combinations were recognized: polymer blends, grafts, and blocks. Although inter penetrating polymer networks, lPNs, were prepared very early in polymer history, and already named by Millar in 1960, they played a relatively low-key role in polymer research developments until the late 1960s and 1970s. I would prefer to consider the IPNs as a subdivision of the graft copolymers. Yet the unique topology of the IPNs imparts properties not easily obtainable without the presence of crosslinking. One of the objectives of this book is to point out the wealth of work done on IPNs or closely related materials. Since many papers and patents actually concerned with IPNs are not so designated, this literature is significantly larger than first imagined. It may also be that many authors will meet each other for the first time on these pages and realize that they are working on a common topology. The number of applications suggested in the patent literature is large and growing. Included are impact-resistant plastics, ion exchange resins, noise-damping materials, a type of thermoplastic elastomer, and many more.
