This book was released on 2013-03-09 with total page 438 pages. Available in PDF, EPUB and Kindle. Book excerpt: Polymer blends, grafts, and blocks, broadly defined, encompass all of the ways in which two or more kinds of poly mer molecules can be mixed and/or joined. Because these mate rials exhibit non-linear and often synergistic properties, they have found increasing application in our technology. Their multifarious uses have, in turn, spurred new research efforts, to find yet different ways of joining two kinds of polymer molecules, with novel physical and/or mechanical behavior patterns. In August, 1973, the Polymer Division of the American Chemical Society sponsored a symposium at its meeting in Chi cago on Polymer Blends, Grafts, and Blocks. This book collects the papers presented at that symposium. Yet, it is more than just a collection of papers, for we here display the thinking and efforts of a number of top-ranking American and foreign scientists in one of the world's more active research areas. The symposium emphasized the interrelationships among synthetic detail, morphology, and physical and mechanical properties. Several novel syntheses were presented. These include oxidation resistant thermoplastic elastomers (Holden), a graft copolymer based thermoplastic elastomer (Kennedy and Smith), a cationic graft copolymer (Kennedy, Charles, and Davidson), an AB crosslinked copolymer (Bamford and Eastmond), an interpenetrating polymer network (Donatelli, Thomas, and Sperling), and simultaneous interpenetrating networks (Frisch, Klempner, Frisch, and Ghiradella). Most polymer blends, grafts, and blocks exhibit two phases. The theory of microdomain structure was discussed (Helfand). The different ways that the two molecules can be joined together was examined (Kenney), and their topology was explored (Sperling).
Download or read book Polymer Blends and Composites written by John A. Manson and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 520 pages. Available in PDF, EPUB and Kindle. Book excerpt: The need for writing a monograph on polymer blends and composites became apparent during presentation of material on this subject to our advanced polymers class. Although the flood of important research in this area in the past decade has resulted in many symposia, edited collections of papers, reviews, contributions to scientific journals, and patents, apparently no organized presentation in book form has been forthcoming. In a closely connected way, another strong impetus for writing this monograph arose out of our research programs in the Materials Research Center at Lehigh University. As part of this effort, we had naturally compiled hundreds of references and become acquainted with many leaders in the field of blend and composite research. Perhaps the most important concept stressed over and over again is that engineering materials are useful because of their complexity, not in spite of it. Blends and composites are toughened because many modes of resistance to failure are available. Although such multimechanism processes are diffi cult to describe with a unified theory. we have presented available develop ments in juxtaposition with the experimental portions. The arguments somewhat resemble the classical discussion of resonance in organic chemistry, where molecular structures increase in stability as more electronic configura tions become available.

Download or read book Polymer Alloys II written by Daniel Klempner and published by Springer Science & Business Media. This book was released on 2013-03-08 with total page 285 pages. Available in PDF, EPUB and Kindle. Book excerpt: The term "alloy" as pertaining to polymers has become an increasingly popular description of composites of polymers, parti cularly since the publication of the first volume in this series in 1977. Polymer alloy refers to that class of macromolecular materials which, in general, consists of combinations of chemically different polymers. The polymers involved in these combinations may be hetero geneous (multiphase) or homogeneous (single phase). They may be linked together with covalent bonds between the component polymers (block copolymers, graft copolymers), linked topologically with no covalent bonds (interpenetrating polymer networks), or not linked at all except physically (polyblends). In addition, they may be linear (thermoplastic), crosslinked (thermosetting), crystalline, or amorphous, although the latter is more common. To the immense satisfaction - but not surprise - of the editors, there has been no decrease in the research and development of polymer alloys since the publication of the first volume, as evidenced by numerous publications, conferences and symposia. Continued advances in polymer technology caused by the design of new types of polymer alloys have also been noted. This technolog ical interest stems from the fact that these materials very often exhibit a synergism in properties achievable only by the formation of polymer alloys. The classic examples, of course, are the high impact plastics, which are either polyblends, block, or graft co polymers composed of a rubbery and a glassy polymer. Interpene trating polymer networks (IPN's) of such polymers also exhibit the same, or even greater, synergism.

This book was released on 2013-05-23 with total page 358 pages. Available in PDF, EPUB and Kindle. Book excerpt: Renowned experts give all essential aspects of the techniques and applications of graft copolymers based on polysaccharides. Polysaccharides are the most abundant natural organic materials and polysaccharide based graft copolymers are of great importance and widely used in various fields. Natural polysaccharides have recently received more attention due to their advantages over synthetic polymers by being non-toxic, biodegradable and available at low cost. Modification of polysaccharides through graft copolymerization improves the properties of polysaccharides. Grafting is known to improve the characteristic properties of the backbones. Such properties include water repellency, thermal stability, flame resistance, dye-ability and resistance towards acid-base attack and abrasion. Polysaccharides and their graft copolymers find extensive applications in diversified fields. Applications of modified polysaccharides include drug delivery devices, controlled release of fungicides, selective water absorption from oil-water emulsions, purification of water etc.

This book was released on 2012-12-06 with total page 361 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many excellent volumes have been written on the chemistry of cellulose and its derivatives. Judging by the number of conferences which have been assembled to deal with the topic, cellulose and its derivatives continue to arouse great scientific interest. Matching this interest has been the development in copolymer science and technology. In both instances the driving force has been the search for products having useful, new or interesting properties. It appeared inevitable that these two concepts would be brought together at some time in the research and development of cellulosic copolymers. That time has arrived. In assembling this text our aim was to present an informative account of the chemistry and technology of cellulosic copolymers. As such, we intended that the contents be of interest to all those concerned with the production and use of cellulosic products whether in academic or industrial circles. Sections of the text should be of value in undergraduate and post-graduate teaching, provided the student is given guidance in following the text. The volume is divided into eight chapters, each dealing with factors which are relevant to an under standing of cellulosic copolymers. Each chapter carries its own bibliography and is reasonably self-contained.

Available in PDF, EPUB and Kindle. Book excerpt: Polymer–Polymer Miscibility discusses miscibility of polymeric mixtures. This book explains the theoretical and practical aspects of polymer miscibility, which has become a considerable area of research in many academic and industrial laboratories. Comprised of seven chapters, this book starts with an overview of the physical nature of the variations of the basic polymer structure. This monograph then discusses the two cases of miscible polymer blends, namely, poly(vinyl chloride) (PVC)–butadiene/acrylonitrile copolymer (NBR) and polystyrene–poly(2,6-dimethyl-1,4-phenylene oxide) (PPO) blends. This text explores the useful and unique properties of blends of poly(vinyl chloride) and butadiene/acrylonitrile copolymer rubber. Other chapters discuss the thermodynamic theories for the phase separation of block copolymers. The reader is also introduced to other variations of chemical structure, which can result in the permanent attachment of polymers to each other through block and graft copolymers. This text also explores the feasibility of covalent bonding of polymer components. This book is intended for chemical engineers and materials scientists.
