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.

From the Introduction PVT data consists of records of the specific volume of a material (or its inverse, the density) as a function of pressure and temperature. There are many reasons why the specific volume of a material will undergo changes: changes in the temperature and pressure (thermal expansion and compression), phase changes (solid-solid phase transitions, melting, crystallization, glass transitions, mesophase transitions), degradation reactions, and many more. Conversely, PVT measurements can be used to study these phenomena and also to yield derivative data of direct importance to engineering applications of materials (compressibility, bulk modulus, thermal expansivity, etc.). PVT methods are part of a wide array of thermoanalytical techniques available to scientists and engineers, but PVT is the only commonly practiced technique that includes pressure as a variable. Polymers are sensitive to pressure: the volume itself, the pressure dependence of transition temperatures, and the kinetics of phase transitions are all significant, not only from a scientific point of view, but also for practical applications in polymer engineering, such as processing. Now published. This unique polymer reference book will be useful to all those involved in polymer research and advanced engineering. The more than 350 tables and graphs provide a wealth of important data in easy-to-use form. The introductory chapter provides details on methodology, equipment use, and information on the many ways in which PVT data can be used in research and engineering.

With its focus on the characterization of nanocomposites using such techniques as x-ray diffraction and spectrometry, light and electron microscopy, thermogravimetric analysis, as well as nuclear magnetic resonance and mass spectroscopy, this book helps to correctly interpret the recorded data. Each chapter introduces a particular characterization method, along with its foundations, and makes the user aware of its benefits, but also of its drawbacks. As a result, the reader will be able to reliably predict the microstructure of the synthesized polymer nanocomposite and its thermal and mechanical properties, and so assess its suitability for a particular application. Belongs on the shelf of every product engineer.

High-Pressure Chemistry and Physics of Polymers is devoted to covering all areas of high-pressure polymer materials science. Topics addressed include the synthesis of polymers, changes in reactivity, structural transformations, molecular dynamics, relaxation processes, deformational properties, chemical modification, and the effect of shock waves and shear stresses. The authors' contributions reflect over 60 years of Soviet study in the field of physico-chemistry conducted at the major former Soviet Institutes of Chemical Physics, Organic Chemistry, Polymer Chemistry, and Physical Chemistry. Fundamental topics such as compressibility of polymers, polymerization under pressure, viscoelastic/deformational properties, and polymer modification are discussed with an eye toward materials development for improving physical models and methods of calculating the changing parameters of materials under pressure. The book is a valuable reference to data on mechanisms of physical and chemical processes, in addition to new experimental data for improving physical models and methods of calculating changes in material characteristics under compression loads. High-Pressure Chemistry and Physics of Polymers will be an important reference for graduate students and practicing professionals in polymer chemistry and polymeric materials.

This Encyclopedia covers the entire science of continuum mechanics including the mechanics of materials and fluids. The encyclopedia comprises mathematical definitions for continuum mechanical modeling, fundamental physical concepts, mechanical modeling methodology, numerical approaches and many fundamental applications. The modelling and analytical techniques are powerful tools in mechanical civil and areospsace engineering, plus in related fields of plasticity, viscoelasticity and rheology. Tensor-based and reference-frame-independent, continuum mechanics has recently found applications in geophysics and materials.
