Download or read book New Frontiers in Polymer Synthesis written by Shiro Kobayashi and published by Springer Science & Business Media. This book was released on 2008-09-26 with total page 196 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is generally accepted that a new material is often developed by ?nding a new synthesis method of reaction or a new reaction catalyst. Historically, a typical example may be referred to as a Ziegler–Natta catalyst, which has allowed large-scale production of petroleum-based polyole?ns since the middle of the 20th century. New polymer synthesis, therefore, will hopefully lead to creation of new polymer materials in the 21st century. This special issue contributed by three groups focuses on recent advances in polymer synthesis methods, which handle the cutting-edge aspects of the advanced technology. The ?rst article by Yokozawa and coworkers contains an overview of the - action control in various condensation polymerizations (polycondensations). Advanced technologies enabled the control of stereochemistry (regio-, g- metrical-, and enantio-selections), chemoselectivity, chain topology, and st- chiometry of monomers, giving a high molecular weight polymer. It has been recognized for a long time, however, that polycondensation is a dif?cult p- cess in controlling the reaction pathway, because the reaction is of step-growth and the reactivity of monomers, oligomers, and polymers are almost the same during the reaction and hence, the molecular weight of polymers and its d- tribution (M /M ) are impossible to regulate. The authors’ group developed w n a new reaction system (chain-growth condensation polymerization), changing the nature of polycondensation from step-growth to chain-growth; namely the propagating chain-end is active, allowing for control of the product molecular weight as well as the distribution.

Available in PDF, EPUB and Kindle. Book excerpt: Polymers are substances containing a large number of structural units joined by the same type of linkage. These substances often form into a chain-like structure. Starch, cellulose, and rubber all possess polymeric properties. Today, the polymer industry has grown to be larger than the aluminium, copper and steel industries combined. Polymers already have a range of applications that far exceeds that of any other class of material available to man. Current applications extend from adhesives, coatings, foams, and packaging materials to textile and industrial fibres, elastomers, and structural plastics. Polymers are also used for most composites, electronic devices, biomedical devices, optical devices, and precursors for many newly developed high-tech ceramics. This new book presents leading-edge research in this rapidly-changing and evolving field.

Available in PDF, EPUB and Kindle. Book excerpt: This book represents the proceedings of the First International Conference on Frontiers of Polymer Research held in New Delhi, India during January 20-25, 1991. Polymers have usually been perceived as substances to be used in insulations, coatings, fabrics, and structural materials. Defying this classical view, polymers are emerging as a new class of materials with potential applications in many new technologies. They also offer challenging opportunities for fundamental research. Recognizing a tremendous growth in world wide interest in polymer research and technology, a truly global "1st International Conference on Frontiers of Polymer Research" was organized by P. N. Prasad (SUNY at Buffalo), F. E. Karasz (University of Massachusetts) and J. K. Nigam (Shriram Institute for Industrial Research, India). The 225 participants represented 25 countries and a wide variety of academic, industrial and government groups. The conference was inaugurated by the Prime Minister of India, Mr. Chandra Shekhar and had a high level media coverage. The focus of the conference was on three frontier areas of polymer research: (i) Polymers for photonics, where nonlinear optical properties of polymers show great promise, (ii) Polymers for electronics, where new conduction mechanisms and photophysics have generated considerable enthusiasm and (iii) High performance polymers as new advanced polymers have exhibited exceptionally high mechanical strength coupled with light weight.

Download or read book New Frontiers in Photochromism written by Masahiro Irie and published by Springer Science & Business Media. This book was released on 2013-05-27 with total page 298 pages. Available in PDF, EPUB and Kindle. Book excerpt: Photochromism is the reversible phototransformation of a chemical species between two forms having different absorption spectra. During the phototransformation not only the absorption spectra but also various physicochemical properties change, such as the refractive index, dielectric constant, oxidation/reduction potential, and geometrical structure. The property changes can be applied to photonic equipment such as erasable memory media, photo-optical switch components, and display devices. This book compiles the accomplishments of the research project titled “New Frontiers in Photochromism” supported by the Ministry of Education, Culture, Sports, Science and Technology of Japan. The project focused not only on the above-mentioned classical subjects in photochromism, such as color changes, optical memory, and optical switches, but also on fundamental physicochemical studies and unprecedented application fields that have not yet been explored in photochromism. The latter topics include light-driven mechanical motion, photocontrol of surface wettability, metal deposition on solid materials, photocontrol of chiral properties, ultrafast decoloration dyes, and femtosecond laser experiments, among others.

Available in PDF, EPUB and Kindle. Book excerpt: Introduction to New Classifications of Polymeric Systems and New Concepts in Chemistry is the first volume of New Frontiers in Sciences, Engineering and the Arts. It is the first, because of the importance of polymers in our lives and world. With life, steroids, DNAs RNAs, enzymes, most of the food we eat, and more are polymeric in character. Without the polymer industry, the largest industry in the whole worldelectrical and electronic industries, Automobiles industries, kitchen and household industries, packaging industries, oil and gas industries, sound and current industries, and more too countless to listcannot exist both in our physical and natural world, a complex world. The greatest subject area in chemistry is polymer chemistry; for without it, one would not have been able to see what the atom is. It was only in recent years that some great scientists began to see that the electron does not exist outside the nucleus of an atom, but probably inside the nucleus. Indeed, where they exist is still unknown to them. What indeed are outside the nucleus are what some great scientists sometimes call radicals. What these radicals are have remained unknown to humanity. For example, how can radicals add during free-radical or radical polymerizations when they have not been identified just like the ions and charges have with, for example, their males and females. One was able to ask this very deep question based on ones background in polymer chemistry at secondary, bachelors, masters, and PhD levels. Otherwise, others can. Finding solutions to it led to the New Frontiers using universal data abundantly available. With this newly added definition for an atom, one discovered that what all scientists, engineers, medical doctors, and experts in all disciplines have been doing have all been based on the use of universal data, 95 percent of which have wrong interpretationsa complete world of illusions. Is it not shocking to note that all chemists, whether polymeric or not, do not know what a monomer or compound is, or how chemical and polymeric reactions take place. Is it not shocking to note that the electrical and electronic engineers do not know how current and sound flows in some metals and liquids and in space. These and so much more are the origins of the New Frontiers, beginning with this first volume wherein new concepts seen in the first book, The Beginning of a New Dawn for Humanity emerged from.

Download or read book Functional Polymers by Post Polymerization Modification written by Patrick Theato and published by John Wiley & Sons. This book was released on 2013-02-12 with total page 431 pages. Available in PDF, EPUB and Kindle. Book excerpt: In modern polymer science a variety of polymerization methods for the direct synthesis of polymers bearing functional groups are known. However, there is still a large number of functional groups that may either completely prevent polymerization or lead to side reactions. Post-polymerization modification, also known as polymer-analogous modification, is an alternative approach to overcome these limitations. It is based on the polymerization of monomers with functional groups that are inert towards the polymerization conditions but allow a quantitative conversion in a subsequent reaction step yielding a broad range of other functional groups. Thus, diverse libraries of functional polymers with identical average degrees of polymerization but variable side chain functionality may easily be generated. Filling the gap for a book dealing with synthetic strategies and recent developments, this volume provides a comprehensive and up-to-date overview of the field of post-polymerization modification. As such, the international team of expert authors covers a wide range of topics, including new synthetic techniques utilizing different reactive groups for post-polymerization modifications with examples ranging from modification of biomimetic and biological polymers to modification of surfaces. With its guidelines this is an indispensable and interdisciplinary reference for scientists working in both academic and industrial polymer research.
