Book Synopsis Structure and Properties of Ionomers by : Michel Pineri
Download or read book Structure and Properties of Ionomers written by Michel Pineri and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 579 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ionomers, that is polymers containing a low concentration of charged units along the chain, have been the subject of increasing interest during the past twenty years. The presence of ionic groups in the poly mer changes some of its properties dramatically. Increases in the modu lus and the viscosity of several orders of magnitude have been observed, and changes in the glass transition of hundreds of degrees are possible. In addition, diffusion coefficients can be modified drastically. These changes are due primarily to the presence of reversible ionic cross links in these materials. Because of the low dielectric constant of most organic polymers, the ions or ionic dipoles tend to aggregate ; this aggregation process, however, is limited, because the ionic groups are covalently bonded to the organic chain. Host of the fundamental research done on these materials has been devoted to a determination of the extent of association, the structure of the aggregates, the limi ting factors, and the correlations between molecular and supermolecular structure and the resul ting properties.
Book Synopsis Ion-Containing Polymers by : A. Eisenberg
Download or read book Ion-Containing Polymers written by A. Eisenberg and published by Elsevier. This book was released on 2012-12-02 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ion-Containing Polymers: Physical Properties and Structure is Volume 2 of the series Polymer Physics. This book aims to fill in the gap in literature regarding the physical aspects of ion-containing polymers. A total of five chapters comprise this book. The Introduction (Chapter 1) generally deals with the application of ion-containing polymers, general classification, and the available works regarding the subject. Chapter 2 establishes the concepts of supermolecular structure and glass transitions in terms of the effects of ionic forces in polymers. These chapters provide the context in the discussion of viscoelastic properties of homopolymers and copolymers in Chapters 3 and 4. Finally, Chapter 5 tackles the configuration-dependent properties of ion-containing polymers. This volume will be of particular help to students in the field of physics and chemistry.

Download or read book Macromolecular Chemistry-11 written by H. Eisenberg and published by Elsevier. This book was released on 2013-10-22 with total page 170 pages. Available in PDF, EPUB and Kindle. Book excerpt: Macromolecular Chemistry — 11 is a collection of lectures presented at the International Symposium on Macromolecules (The Third Aharon Katzir-Katchalsky Conference) held in Jerusalem, Israel, on July 13-18, 1975. The papers explore a wide range of topics related to macromolecular chemistry, including polyelectrolytes, biologically active synthetic polymers, and spans of polymer chains. The use of polymers as chemical reagents is also considered. This book is comprised of 19 chapters and begins with an introduction to the close relation between polyelectrolytes and hydrophilic colloids. A survey of polyelectrolyte knowledge that has accumulated since about 1940 is also presented. The discussion then turns to biologically active synthetic polymers; polymers and other composites; theories of the condensed polymer state; polymer adsorption inferred from electrical double layer measurements; and mobility and conductivity of ions in and into polymeric solids. The structure and viscoelastic properties of ion-containing polymers in the solid state are also examined, along with the use of graphite insertion compounds as chemical reagents in organic chemistry. The results of research on chemical modification of cellulose are also presented. This monograph will be of interest to chemists.

Download or read book Developments in Ionic Polymers—2 written by A.D. Wilson and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 364 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ionic polymers, like elephants, are easier to recognise than to define. Several methods of classification have been attempted but none is wholly satisfactory because of the extreme diversity of ionic polymers, which range from the organic, water-soluble polyelectrolytes, through hydrogels and ionomer carboxylate rubbers, to the almost infusible inorganic silicate minerals. For this reason, a general classification is not only difficult, but has minimal utility. However, there are some characteristics of these materials that should be highlighted. The role of counterions is the significant one. These ions, either singly or as clusters, take part in the formation of ionic bonds which have a varying structural role. Often they act as crosslinks, but in the halato-polymers the ionic bonds form an integral part of the polymer backbone itself. Conversely, in polymers contain ing covalent crosslinks, such as the ion-exchange resins, the coun terions have virtually no structural role to play, since they dwell in cage-like structures without affecting the crosslinking, and are readily exchanged. They are, perhaps, best described as ion-containing polymers rather than structural ionic polymers. Another crucial factor is the role of water in ionic polymers. The presence of ionic bonds means that there is a tendency for these materials to interact with water. Where the ionic polymer contains a high proportion of ionic units, it acts as a hydrogel and may be highly soluble. Such interactions with water decrease sharply as the ionic content is reduced, though even then water can act as a plasticiser.

Available in PDF, EPUB and Kindle. Book excerpt: Polymers have achieved an enviable position as the class of materials having the highest volume of production, exceeding that of both metals and ceramics. The meteoric rise in the production and utilization of polymers has been due to advances in polymer synthesis which allow the creation of specific and well-defined molecular structures, to new knowledge concerning the relationships between polymer structure and properties, and to an improved understanding of how processing can be used as a tool to develop morphological features which result in desired properties. Polymers have truly become 'engineered materials' in every sense of the term. Polymer scientists and engineers are forever seeking to modify and improve the properties of synthetic polymeric systems for use in specific applications. Towards this end they have often looked to nature for advice on how to design molecules for specific needs. An excellent illustration of this is the use of noncovalent bonding (ionic, hydrogen, and van der Waals) in lipids, proteins, and nucleic acids, where these noncovalent bonds, acting both intra and intermolecularly, precisely control the structure and thus the function of the entire system. The utilization of ionic bonding, in particular in man-made polymers has attracted widespread interest in recent years, since ionic interactions exert a similar strong influence on the structure and properties of these synthetic systems.
