Polymerie materials have been replacing other conventional materials like metals, glass and wood in a number of applications. The use of various types of fillers incorporated into the polymer has become quite common as a means of reducing cost and to impart certain desirable mechanieal, thermal, electrieal and magnetic properties to the polymers. Oue to the energy crisis and high priees of petrochemieals, there has been a greater demand to use more and more fillers to cheapen the polymerie materials while maintaining and/or improving their properties. The advantages that filled polymer systems have to offer are normally offset to some extent by the increased complexity in the rheological behavior that is introduced by the inclusion of the fillers. Usually when the use of fillers is considered, a compromise has to be made between the improved mechanieal properties in the solid state, the increased difficulty in melt processing, the problem of achieving uniform dispersion of the filler in the polymer matrix and the economics of the process due to the added step of compounding. It has been recognized that addition of filler to the polymer brings a change in processing behavior. The presence of the filler increases the melt viscosity leading to increases in the pressure drop across the die but gives rise to less die swell due to decreased melt elasticity.

The present book is devoted to a rapidly developing field of science which studies the behavior of viscoelastic materials under the influence of deformation~the rheology of polymers. Rheology has long been treated as the theoretical foundation of polymer processing, and from this standpoint it is difficult to overesti mate its importance in practice. Rheology plays an important role in developing our ideas on the nature of viscoelastic behavior in connection with the structural features of polymers and composites based on them. This expands the possibilities of employing rheological methods to characterize a variety of materials and greatly magnifies the interest in this field of research. The rheological properties of polymer systems are studied experimen tally, chiefly under conditions of shear and tensile strains. One explana tion is that many aspects of polymer material processing are associated with the stretching of melts or a combination of shear and tensile strains. In scientific investigations, either periodic or continuous conditions of shear deformation are employed. Each mode provides widespread infor mation. In periodic deformation, most attention is generally given to conditions with low deformation amplitudes that do not alter the structure of the polymer system during an experiment (the region of linear deformation conditions). Here the viscoelastic parameters are generally determined with respect to the frequency. Continuous deforma tion involves considerable strains, and may be attended by significant reversible and irreversible changes in the structure of a polymer.

Explore polymer rheology from an industrial standpoint Presenting state-of-the-art polymer rheology as observed by well-recognized authors, Applied Polymer Rheology: Polymeric Fluids with Industrial Applications is designed to help readers understand the relationship between molecular structure and the flow behavior of polymers. In particular, it focuses on polymeric systems that elicit special attention from industry. Providing a comprehensive overview of the rheological characteristics of polymeric fluids, the book bridges the gap between theory and practice/application, enabling readers to see the connection between molecular structure and the behavior of the polymers studied. Beginning with a discussion of the properties, processability, and processing aids of specific polymers, later chapters examine filled polymers and composites, and the theoretical framework upon which their analysis is based. Various systems containing microstructure are presented subsequently, with the final chapter introducing paste extrusion of polytetrafluoroethylene paste. An invaluable reference guide that covers the literature and vast array of technical approaches to polymer rheology, Applied Polymer Rheology's coverage of polymeric fluids of interest to industry make it an essential resource for plastics, polymer, and chemical engineers, materials scientists, polymer chemists, and polymer physicists to use when interpreting findings and planning experiments.

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.

This book is aimed at scientists and practicing engineers who are currently exploring or would like to explore the complexity of fabrication processes of polymer composites. It deals with the mechanics and modeling aspects of discontinuous and continuous fiber composites and familarizes the engineer with the critical and fundamental issues of material processing and transport phenomena in polymeric composites and their applications in modeling and simulating specific composite manufacturing processes. Divided into three parts, Part A deals with the deformation science or rheology of these filled materials. It clearly shows the need to characterize their flow behavior before one can draw any conclusions about its processibility during manufacturing. Part B focuses on development of constitutive equations to describe the flow and deformation behavior of such materials under external processing conditions. Part C discusses the mathematical models for selected composite processes and their implementation into a computer simulation to analyze the process behavior. The processes represented in Part C cover a cross-section of important manufacturing processes and maintain a balance between processes that use short fibers and continuous fibrous materials.

This conference on the Rheology of Polymer Systems was held at the Institute of Macromolecular Chemistry of the Academy of Sciences of the Czech Republic in Prague from 19-22nd July 1999, as part of the Prague Meetings on Macromolecules sponsored, as usual, by IUPAC. The topics covered included relations between rheological properties and structure of molten polymer systems, advanced rheometry and rheological characterization, interrelations between rheological data measured in various flow fields and progress in the description of complex flow of molten polymer systems. The papers within this volume of Macromolecular Symposia cover a broad range of topics typical of the symposium.
