Download or read book New Frontiers in Polymer Research written by Robert K. Bregg and published by Nova Publishers. This book was released on 2006 with total page 252 pages. 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: 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.

Download or read book Branched Polymers I written by Jaques Roovers and published by Springer. This book was released on 2003-07-01 with total page 251 pages. Available in PDF, EPUB and Kindle. Book excerpt: While books have been written on many topics of Polymer Science, no compre hensive treatise on long chain branching has ever been composed. This series of reviews in Volume 142 and 143 of Advances in Polymer Science tries to fill this gap by highlighting active areas of research on branched polymers. Long chain branching is a phenomenon observed in synthetic polymers and in some natural polysaccharides. It has long been recognized as a major mole cular parameter of macromolecules. Its presence was first surmised by H. Stau dinger and G. V. Schuh (Ber. 68, 2320, 1935). Interestingly, their method of iden tification by means of the abnormal relation between intrinsic viscosity and molecular weight has survived to this day. Indeed, the most sophisticated method for analysis of long chain branching uses size exclusion fractionation with the simultaneous recording of mass, molecular weight and intrinsic visco sity of the fractions. In the 1940s and 1950s, random branching in polymers and its effect on their properties was studied by Stockmayer, Flory, Zimm and many others. Their work remains a milestone on the subject to this day. Flory dedicated several chapters of his "Principles of Polymer Chemistry" to non linear polymers. Especially important at that time was the view that randomly branched polymers are inter mediates to polymeric networks. Further developments in randomly branched polymers came from the introduction of percolation theory. The modern aspec ts of this topic are elaborated here in the chapter by W. Burchard.

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.
