Available in PDF, EPUB and Kindle. Book excerpt: Block polymers represent another milestone in the preparation of polymers of controlled structure. Catalysts and polymerization methods that allowed the preparation of polymers in which the stereo- and geometric isomerism of the monomer units could be con trolled have indeed been among the major developments in polymer science during the last decade. The synthesis of block polymers, in which the sequence length of the comonomer units can be con trolled, portends equally important developments in the science and technology of polymers. The papers collected in this volume cover primarily the pro ceedings of the most recent symposium on block polymers, sponsored by the Division of Polymer Chemistry of the American Chemical Society. It was held in New York City during the Society's 158th National Meeting in September, 1969. Additional contributions from selected authors were invited especially for this book to achieve the most up-to-date account of the advances that have been made since the development of the thermoplastic elastomers that first brought into focus this important area of research. The first two papers in this volume draw attention to the various problems that should be considered in the preparation of block polymers of precisely defined structure from styrene and butadiene or isoprene by anionic polymerization. Characterization of block polymers presents many problems and there is a paucity of systematic work in this area. Attention has been given to the di lute solution properties of block polymers,however, in one of the papers in this volume.

This book was released on 2012-12-06 with total page 234 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first concern of scientists who are interested in synthetic polymers has always been, and still is: How are they synthesized? But right after this comes the question: What have I made, and for what is it good? This leads to the important topic of the structure-property relations to which this book is devoted. Polymers are very large and very complicated systems; their character ization has to begin with the chemical composition, configuration, and con formation of the individual molecule. The first chapter is devoted to this broad objective. The immediate physical consequences, discussed in the second chapter, form the basis for the physical nature of polymers: the supermolecular interactions and arrangements of the individual macromolecules. The third chapter deals with the important question: How are these chemical and physical structures experimentally determined? The existing methods for polymer characterization are enumerated and discussed in this chapter. The following chapters go into more detail. For most applications-textiles, films, molded or extruded objects of all kinds-the mechanical and the thermal behaviors of polymers are of pre ponderant importance, followed by optical and electric properties. Chapters 4 through 9 describe how such properties are rooted in and dependent on the chemical structure. More-detailed considerations are given to certain particularly important and critical properties such as the solubility and permeability of polymeric systems. Macromolecules are not always the final goal of the chemist-they may act as intermediates, reactants, or catalysts. This topic is presented in Chapters 10 and 11.

Download or read book Polymer Solutions Blends and Interfaces written by I. Noda and published by Elsevier. This book was released on 2012-12-02 with total page 498 pages. Available in PDF, EPUB and Kindle. Book excerpt: The behaviour of polymers in multi-component and multiphase systems such as solutions, blends and interfaces derived from both natural and synthetic sources and the subsequent influence of this on their physical properties is the theme of this book. Important new material on multiphase polymer systems such as block copolymers and liquid crystalline polymers is provided, and the solution and surface properties of enzymes and surface active polymers is described both theoretically and experimentally. The application of theory to the development of new cellulosic materials is particularly noteworthy. The relationship between end-use properties, such as adhesion, wetting, and colloidal stability, and molecular structure at the interface is addressed. Examples include the capillary pressure of nylon microporous membranes, a new technique for characterizing the adhesion between incompatible polymers, and the influence of the glass transition temperature at the fiber/matrix interface on interfacial shear strength. Characterization of polymer films, both electrochemically and via optical techniques is covered and the interactions of amphiphilic ions with polyacrylate polymer are described. The final two chapters introduce the topic of enzyme mobility at an interface and show how this may affect their role as biological catalysts.
Download or read book Characterization of Polymer Blends written by Sabu Thomas and published by John Wiley & Sons. This book was released on 2015-02-09 with total page 972 pages. Available in PDF, EPUB and Kindle. Book excerpt: Filling the gap for a reference dedicated to the characterization of polymer blends and their micro and nano morphologies, this book provides comprehensive, systematic coverage in a one-stop, two-volume resource for all those working in the field. Leading researchers from industry and academia, as well as from government and private research institutions around the world summarize recent technical advances in chapters devoted to their individual contributions. In so doing, they examine a wide range of modern characterization techniques, from microscopy and spectroscopy to diffraction, thermal analysis, rheology, mechanical measurements and chromatography. These methods are compared with each other to assist in determining the best solution for both fundamental and applied problems, paying attention to the characterization of nanoscale miscibility and interfaces, both in blends involving copolymers and in immiscible blends. The thermodynamics, miscibility, phase separation, morphology and interfaces in polymer blends are also discussed in light of new insights involving the nanoscopic scale. Finally, the authors detail the processing-morphology-property relationships of polymer blends, as well as the influence of processing on the generation of micro and nano morphologies, and the dependence of these morphologies on the properties of blends. Hot topics such as compatibilization through nanoparticles, miscibility of new biopolymers and nanoscale investigations of interfaces in blends are also addressed. With its application-oriented approach, handpicked selection of topics and expert contributors, this is an outstanding survey for anyone involved in the field of polymer blends for advanced technologies.

This book was released on 2012-12-06 with total page 266 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book contains a collection of original research papers which were presented in honor of the Bordon Award recipient, Professor Eric Baer, on the occasion of the 55th Meeting of the American Chemical Society (Atlanta, Georgia, March, 1981). The contributors are present or former colleagues and students who have worked with him in the Department of Macromolecular Science at Case Institute of Technology of Case Western Reserve University. Throughout his work, Eric Baer has attempted to find the relation ships of solid state structure and hierarchy to the resultant pro perties from which specific functions are derived. Although he has studied many seemingly unrelated subjects, from irreversible de formation, mechanics and yield processes in amorphous polymeric solids to structural organization and mechanical function of ten don, his unique goal has been to develop models from the real structure that would allow a quantitative description of properties. Today, this area of "microscience" is rapidly expanding as new and sophisticated applications of polymeric materials with multifunc tional properties are emerging from our understanding and control of the solid state. The wide-ranging ideas and the original ity of Professor Baer's contributions have stimulated many new concepts which are now widely accepted in the field of high polymers. The contributions to this volume represent many of the areas which he has explored.
