Book excerpt: The problems related to crazing in polymers are of special interest to polymer scientists since only polymers display this universal phenomenon and no analogues are available for low-molecular-mass compounds. The important problems of solvent crazing and the development of a universal description of polymer structure and properties have received much attention from many leading scientists. Nevertheless, some aspects of polymer crazing are still unclear, and scientific activities in this area are in progress. This work provides an up-to-date account of scientific advances in the area of solvent crazing. The principal features and stages of solvent crazing (craze nucleation, craze tip advance, craze thickening, and craze collapse at high strains) are described. Additionally, the authors present information concerning the activities of Russian scientists in this area, which might have escaped the attention of their colleagues because of the language barrier.

Available in PDF, EPUB and Kindle. Book excerpt: Simultaneous action of stress and strain on plastics in contact with specific fluids causes the onset of cracking and embrittlement of plastic known as environmental stress cracking. Since this is responsible for 15% of all failures of plastics components, environmental stress cracking has long been the subject of intensive research. This volume reviews factors that influence environmental stress cracking, and the state of knowledge regarding many families of plastics. Various types of damage, from disfiguring to catastrophic, are discussed in this volume, with the period of time over which the damage occurs. Plastics designers and specifiers will benefit from the wealth of information and data provided.

Available in PDF, EPUB and Kindle. Book excerpt: Transparent polymers being considered for use in Army systems must be evaluated for resistance to crack and craze growth in a chemical environment. Current test for determining craze initiation include environmental stress crazing tests based on ASTM D 790 and ASTM F 484. Results for a series of cast and biaxially stretched poly(methyl methacrylate) (PMMA) materials, as well as several formulations of polycarbonate, show a range of critical strain measurements in crazing solvents. A polyurethane based thermoset material showed superior resistance to crazing in several of these solvents. The effect of solvents on crack propagation in transparent polymers is demonstrated by a Samples of PMMA are tested in o-xylene, and air. Immersion testing is also used for comparison.

Book excerpt: A two point bending method for use in studying the environmental stress cracking and crazing phenomena is described and demonstrated for a variety of polymer/solvent systems. Critical strain values obtained from these curves are reported for various polymer/solvent systems including a considerable number of systems for which critical strain values have not been previously reported. Polymers studied using this technique include polycarbonate (PC), ABS, high impact styrene (HIS), polyphenylene oxide (PPO), and polymethyl methacrylate (PMMA). Critical strain values obtained using this method compared favorably with available existing data. The major advantage of the technique is the ability to obtain time vs. strain curves over a short period of time. This allows, in most cases, sensitive determination of the nature of the transition between the time independent portion and the time dependent portion of the time vs. strain curve. The data obtained suggests that over a short period of time the transition in most of the polymer solvent systems is more gradual than previously believed. Studies of the temperature effects in the PC/MIBK, PC/Cyclohexanone, and PPO/MIBK systems give results consistent with previous studies that support a plasticization mechanism for environmental stress cracking and crazing.

Available in PDF, EPUB and Kindle. Book excerpt: The synthetic counterparts of natural polymeric materials are now finding applications as light weight, mechanically strong, and environmentally stable sheets, fibers, films, adhesives, paints, and foams have replaced most of the commodity and structural materials. The systematic research on the preparation, characterization, and utilization of plastics resulted in creation of polymers often containing a set of several desirable properties in a single polymer. The polymers have established their place in engineering applications as well. Although the bulk of plastics production focuses on relatively simple commodity polymers, the proportion of specially designed and tailor-made plastics for specific and sophisticated applications is also increasing at a great pace. The specialty plastics, as well as their use in specific and sophisticated applications, are the key to the continued scientific growth and technological advances in the new millennium. This book thoroughly covers today's rapidly growing field of specialty polymers and their applications in more sophisticated and specialized areas. It gives the most recent in-depth knowledge and extremely comprehensive details of the chemistry, physics, material science, technology, and device applications of specialty polymers. This comprehensive book containing 16 chapters is the result of the untiring efforts of 35 most renowned experts from the national and international scientific community. This book is thought-provoking to the researchers working in the fields of chemistry, biochemistry, biotechnology, medicine, polymer chemistry, semiconductor physics, material science, electrochemistry, biology, electronics, photonics, material science, solid state physics, nanotechnology, electrical and electronics engineering, optical engineering, device engineering, data storage, etc.

Available in PDF, EPUB and Kindle. Book excerpt: This work sets out to provide an up-to-date account of the physical properties and structure of polymers in the glassy state. Properties measured above the glass transition temperature are therefore included only in so far as is necessary for the treatment of the glass transition process. This approach to the subject therefore excludes any detailed account of rubber elasticity or melt rheology or of the structure and conformation of the long chain molecule in solution, although knowledge derived from this field is assumed where required. Major emphasis is placed on structural and mechanical properties, although a number of other physical properties are included. Naturally the different authors contributing to the book write mainly from their own particular points of view and where there are several widely accepted theoretical approaches to a subject, these are sometimes provided in different chapters which will necessarily overlap to a significant extent. For example, the main theoretical presentation on the subject of glass transition is given in Chapter 1. This is supplemented by accounts of the free volume theory in Chapter 3 and in the Introduction, and a short account of the work of Gibbs and DiMarzio, also in Chapter 3. Similarly, there is material on solvent cracking in Chapters 7 and 9, though the two workers approach the subject from opposite directions. Every effort has therefore been made to encourage cross-referencing between different chapters.

Available in PDF, EPUB and Kindle. Book excerpt: My heart sank when I was approached by Dr Hastings and by Professor Briggs (Senior Editor of Materials Science and Technology and Series Editor of Polymer Science and Technology Series at Chapman & Hall, respectively) to edit a book with the provisional title Handbook of Poly propylene. My reluctance was due to the fact that my former book [1] along with that of Moore [2], issued in the meantime, seemed to cover the information demand on polypropylene and related systems. Encour aged, however, by some colleagues (the new generation of scientists and engineers needs a good reference book with easy information retrieval, and the development with metallocene catalysts deserves a new update!), I started on this venture. Having some experience with polypropylene systems and being aware of the current literature, it was easy to settle the titles for the book chapters and also to select and approach the most suitable potential contributors. Fortunately, many of my first-choice authors accepted the invitation to contribute. Like all editors of multi-author volumes, I recognize that obtaining contributors follows an S-type curve of asymptotic saturation when the number of willing contributors is plotted as a function of time. The saturation point is, however, never reached and as a consequence, Dear Reader, you will also find some topics of some relevance which are not explicitly treated in this book (but, believe me, I have considered them).

Available in PDF, EPUB and Kindle. Book excerpt: This book on "Polymer Fracture" might as well have been called "Kinetic Theory of Polymer Fracture". The term "kinetic theory", however, needs some de finition or, at least, some explanation. A kinetic theory deals with and particu larly considers the effect of the existence and discrete size, of the motion and of the physical properties of molecules on the macroscopic behavior of an ensemble, gaseous or other. A kinetic theory of strength does have to consider additional aspects such as elastic and anelastic deformations, chemical and physical reactions, and the sequence and distribution of different disintegration steps. In the last fifteen years considerable progress has been made in the latter do mains. The deformation and rupture of molecular chains, crystals, and morphologi cal structures have been intensively investigated. The understanding of the effect of those processes on the strength of polymeric materials has especially been furthered by the development and application of spectroscopical methods (ESR, IR) and of the tools offracture mechanics. It is the aim of this book to relate the conventional and successful statistical, parametrical, and continuum mechanical treatment of fracture phenomena to new results on the behavior of highly stressed molecular chains.
