Book Description
Experts in rheology and polymer processing present up-to-date, fundamental and applied information on the rheological properties of polymers, in particular those relevant to processing, contributing to the physical understanding and the mathematical modelling of polymer processing sequences. Basic concepts of non-Newtonian fluid mechanics, micro-rheological modelling and constitutive modelling are reviewed, and rheological measurements are described. Topics with practical relevance are debated, such as linear viscoelasticity, converging and diverging flows, and the rheology of multiphase systems. Approximation methods are discussed for the computer modelling of polymer melt flow. Subsequently, polymer processing technologies are studied from both simulation and engineering perspectives. Mixing, crystallization and reactive processing aspects are also included. Audience: An integrated and complete view of polymer processing and rheology, important to institutions and individuals engaged in the characterisation, testing, compounding, modification and processing of polymeric materials. Can also support academic polymer processing engineering programs.

Book Description
Phase morphology in multicomponent polymer-based systems represents the main physical characteristic that allows for control of the material design and implicitly the development of new plastics. Emphasizing properties of these promising new materials in both solution and solid phase, this book describes the preparation, processing, properties, and practical implications of advanced multiphase systems from macro to nanoscales. It covers a wide range of systems including copolymers, polymer blends, polymer composites, gels, interpenetrating polymers, and layered polymer/metal structures, describing aspects of polymer science, engineering, and technology. The book analyzes experimental and theoretical aspects regarding the thermal and electrical transport phenomena and magnetic properties of crucial importance in advanced technologies. It reviews the most recent advances concerning morphological, rheological, interfacial, physical, fire-resistant, thermophysical, and biomedical properties of multiphase polymer systems. Concomitantly the book deals with basic investigation techniques that are sensitive in elucidating the features of each phase. It also discusses the latest research trends that offer new solutions for advanced bio- and nanotechnologies. Introduces an overview of recent studies in the area of multiphase polymer systems, their micro- and nanostructural evolutions in advanced technologies, and provides future outlooks, new challenges and opportunities. Discusses multicomponent structures that offer enhanced physical, mechanical, thermal, electrical, magnetic, and optical properties adapted to current requirements of modern technologies. Covers a wide range of materials, such as composites, blends, alloys, gels and interpenetrating polymer networks. Presents new strategies for controlling the micro- and nanomorphology and the mechanical properties of multiphase polymeric materials. Describes different applications of multiphase polymeric materials in various fields, including automotive, aeronautics and space industry, displays, and medicine.

Book Description
Multiphase Flow in Polymer Processing focuses on dispersed and stratified multiphase flow in polymer processing. This book explores the rheological behavior of multiphase (or multicomponent) polymeric systems as they are involved in various fabrication operations. It also outlines the importance of the morphological states of multiphase polymeric systems to explain the systems, rheological behavior in the fluid state, and mechanical behavior in the solid state. This monograph consists of eight chapters divided into two parts. After discussing dispersed and stratified multiphase flow in polymer processing, it introduces the reader to the fundamentals of rheology. The following chapters focus on the rheological behavior of particulate-filled polymeric systems and heterogeneous polymeric systems; the phenomenon of droplet breakup in dispersed flow; and gas-charged polymeric systems. The role of the discrete phase (that is, solid particles, liquid droplets, gas bubbles) in determining the bulk rheological properties of the multiphase system is highlighted, along with some representative polymer processing operations (namely, fiber spinning and injection molding) of the multiphase (or multicomponent) polymeric systems. Coextrusion in cylindrical, rectangular, and annular dies is also considered. The final chapter is devoted to the phenomenon of interfacial instability in coextrusion. This text will be a useful resource for chemists, chemical engineers, and those in the polymer processing industry.

Book Description
FROM THE PREFACE Almost all polymeric systems are subjected to a flow field at least once along the route between preparation and application. . . . There is also an increased interest in predictive models on phase behavior and suitable techniques for characterizing the structure of these systems when subjected to flow. Multiphase polymeric systems are particularly susceptible to flow, which may cause orientation of species, morphological changes, and phase transitions. All these events may, in turn, affect the end product properties, such as permeability, electrical conductivity, [and] mechanical properties. In processing, escalating needs have evolved for optimization and development of novel and more uniform product properties and increased productivity. In order to arrive at an understanding of processing polymeric systems under elastic flow conditions, it is convenient to analyze the basic physical mechanisms under conditions that enable development of predictive models in conjunction with controlled experimentation. . . . In recent years, the science of rheo-physics has evolved and now involves both advanced theories and experimental techniques. Rheo-physics means the rheological, morphological, and thermodynamic behavior of structured polymer systems during flow. . . . In this monograph, the rheo-optical techniques are . . . emphasized. The book gives an introduction to rheo-physics, including fundamentals of theories, and a representative selection of applications of rheo-optical techniques for analyzing multiphase systems. The chapters contain both practical advice for the new experimenter . . . as well as review material for the experienced scientist.
