Available in PDF, EPUB and Kindle. Book excerpt: Rapid advances in technology require materials with improved property profiles. Polymer modification using grafting and crosslinking are key ways to achieve this in an economical way and without the need for developing new materials. Often widely disparate and in a number of references, practical information on polymer grafting and crosslinking is now available in one volume. Researchers seeking information that bridges the knowledge gap between the scientific principles and industrial applications of polymer crosslinking and grafting will find coverage on the basic science, the methodologies, and a focus on the specific techniques used in a variety of industrial applications such as automotive, laminates, paints, adhesives, and cable. Coverage also includes potential biomedical applications. Descriptions of analytical tools that can be used to evaluate the results are also included.

Download or read book Radiation Processing of Polymer Materials and Its Industrial Applications written by Keizo Makuuchi and published by John Wiley & Sons. This book was released on 2012-02-07 with total page 448 pages. Available in PDF, EPUB and Kindle. Book excerpt: This text examines the effect of radiation on polymers and the versatility of its industrial applications. By helping readers understand and solve problems associated with radiation processing of polymers, it serves as an important reference and fills a gap in the literature. Radiation processing can significantly improve important properties of polymers, however, there are still misconceptions about processing polymers by using ionizing radiation. This book explains the radiation processing of polymeric materials used in many industrial products including cars, airplanes, computers, and TVs. It even addresses emerging "green" issues like biomaterials and hydrogels.

Available in PDF, EPUB and Kindle. Book excerpt: Hydrogen abstraction can be forced to occur either from the pendant group or the chain backbone, leading to systems in which chain scission is not possible and combination can be exclusively selected. Non-radical based crosslinking chemistries can also be used to produce crosslinks without risk of chain scission. These findings have a wide applicability in many fields and implications for the improved design of radical-based crosslinking systems.

Download or read book Structure and Properties of Crosslinked Polymers written by Gasan M Magomedov and published by Smithers Rapra. This book was released on 2011-03-23 with total page 502 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book gives a fresh point of view on the curing processes, structure and properties of crosslinked polymers. The general view is that the structure and properties of crosslinked polymers are defined by their density, this book demonstrates that the parameters are defined by the supermolecular (a more precisely, supersegmental structure) of the crosslinked polymers.The quantitative relationships of the structures/properties are obtained for these polymers. Using an epoxy polymer as a nanofiller for a nanocomposite is discussed and a new class of polymer is proposed. The introduction of the nanofiller gives variation in the mechanical properties, degree of crystallinity, gas permeability and so on. The use of these crosslinked polymers as natural nanocomposites is proposed. Practical methods of crosslinked polymer's supersegmental structure regulation are considered, and all the changes that this gives their properties are detailed.This book will be of significance to all material scientists and students of material science.

Download or read book Chemical Transformations of Polymers written by R. Rado and published by Elsevier. This book was released on 2018-03-05 with total page 307 pages. Available in PDF, EPUB and Kindle. Book excerpt: Chemical Transformations of Polymers provides information pertinent to the fundamental structure and aspects of the chemical transformation of polymers. This book examines several experiments for the chemical transformation of polymers, which start from the assumption that the reactivity of a functional group in a macromolecule has to be similar as one in a low molecular compound. Organized into 19 chapters, this book begins with an overview of the various photochromic systems that have been used in polymer chemistry. This text then examines the three types of stable polymers with unpaired electrons, including polyradical ions, neutral polyradicals, and polymeric charge transfer complexes. Other chapters consider the kinetic laws and traits of migration mechanisms of free valence in the process of decay of free radicals in polymers. The final chapter deals with the complicated reaction of the degradation of polymers induced by the presence of metal compounds. This book is a valuable resource for chemists, scientists, and physiochemical researchers.
