Rheology Principles, Measurements, and Applications Christopher W. Macosko If you use rheological measurements to characterize new materials, analyze non-Newtonian flow problems, or design plastic parts, or if you would like to use rheology to overcome a particular problem, this volume will prove invaluable to your research. Rheology: Principles, Measurements, and Applications presents an extremely practical, timely, and accessible three-dimensional account of the subject. It has been specifically designed to enable researchers to understand and apply information from the latest rheological literature to their own operations. Worked examples and exercises with solutions make it ideal for self-study. This book covers the essential criteria for selecting the best test types for various applications, accurately interpreting results, and determining other areas where rheology and rheological phenomena may be useful in your work. Section one develops important constitutive equations using simple deformations; section two explores shear and extensional rheometers, techniques for measuring material functions, and optical methods in rheology; and section three discusses applications of rheology to polymeric liquid and dispersions. Rheology: Principles, Measurements, and Applications will be of greatest interest to chemical engineers, chemists, polymer scientists, and mechanical engineers, as well as students in these and related fields.

The topics covered in this volume include relations between rheological properties and structure of molten polymer systems, and interrelations between rheological data measured in various flow fields and progress in the description of complex flow of molten polymer systems

This volume presents the main results obtained by different laboratories involved in the research group "Rheology for polymer melt processing" which is associated with French universities, schools of engineering and the CNRS (Centre Nationale de la Recherche Scientifique - France). The group comprises some 15 research laboratories of varied disciplines (chemistry, physics, material sciences, mechanics and mathematics), but with a common challenge: to enhance the understanding of the relationships between macromolecular species, their rheology and their processing. Issues of polymer science addressed include: correlation of viscoelastic macroscopic bulk property measurements and models; slip at the wall; extrusion defects; correlation between numerical flow simulations and experiments

Book Description
Provides the basic background needed by engineers to determine experimentally and interpret the rheological behavior of polymer melts--including not only traditional pure melts but also solutions and compounds containing anisotropic (fiber or disc) or colloidal particles--and apply it to analyze flow in processing operations. Experimental foundations of modern rheology and rheo-optics and the interpretation of experimental data are covered, which also develops the fundamentals of continuum mechanics and shows how it may be applied to devise methods for measurement of rheological properties, formulation of three-dimensional stress-deformation relationships, and analysis of flow in processing operations. Also discusses the structure of polymers and considers rheological behavior in terms of structure. Constitutive equations relating stress to deformation history in non-Newtonian fluids and their applications are discussed. Each chapter presents an overview of the subject matter and then develops the material in a pedagogical manner.

Synopsis
This volume describes how to experimentally determine and interpret the rheological behaviour of polymer melts, then analyze flow in processing operations. It develops the fundamentals of continuum mechanics and shows how to devise methods for measurement of rheological properties, formulation of 3-dimensional stress-deformation relationships and analysis of flow in processing operations. The structure of polymers is described and rheological behaviour interpreted in terms of these structures. The book also discusses polymer fabrication technology and how to analyze and design these processes. Each chapter comprises a critical historical survey followed by a concise development of the topic

Synopsis
This monograph contains the fundamentals of the theory and gives a compact and consistent picture of the different relaxation phenomena in very concentrated solutions and melts of linear polymers (diffusion, neutron scattering, viscoelasticity, and optical birefringence) from a macromolecular point of view and without any specific hypotheses. It can be considered as a complementary reading to the textbook by Doi and Edwards. The original approach taken to the problem allows us to understand why numerous attempts to find the 3.4-index law for the viscosity co-efficient of linear polymers in the frame of the reptation-tube model were doomed to fail, and have failed during the last 20 years. It also helps us to derive the proper constitutive relation for polymers of different architecture. The monograph can be used as a textbook for graduate students with some background in physics and mathematics. It could also provide material for a one- or two-semester graduate-level course in polymer dynamics. The monograph presents topics in a self-contained way that makes it a suitable reference book for professional researchers in the fields of rheology, polymer science, polymer engineering, and material science

Rheology is the science and technology that deals with the deformation of polymeric or plastic materials. In this monograph the field of polymer rheology is explained with emphasis on the chemical theory. The book provides basic information on rheology for nonspecialists and gives explanations of the various phenomena. The author has developed a new theory of thermodynamics and kinetics using a model of multi-size pseudo crosslinks that provides a comprehensive principle to show how links in chain molecules affect the melting temperatures and determine polymer properties such as viscoelasticity, melt viscosity and elastic and plastic behaviour of bulk polymers. The theory can be extended to include the strength of rubber and plastics, active fillers and adhesion, friction and abrasion.

The behavior of polymer solutions in elongational flow has been treated quite recently in the literature but scattered in disparate scientific journals not easily accessible. This is very surprising since elongational flow is known to be very effective on polymer chains and thus more interesting than the already wellknown shear flow. This book covers for the first time the subject from the point of view of the various disciplines. It achieves a balance between science, experiment and technology and integrates the fundamental and practical aspects.

The rheology of filled polymer systems is an ever expanding field in the polymer industry today. Using a concise, practical and simple format this comprehensive work explains the concepts behind filled polymer systems and the rheological techniques involved in studying their behaviour. Covering such topics as preparation of filled polymer systems, steady shear viscous properties and extensional flow properties, this book covers areas from an introductory level through to more complex issues.

"Polymer Alloys and Blends" is a book dedicated to fundamentals of polymer blend science and technology. The text provides both a description of the basic principles and a review of the developments in thermodynamics, rheology and morphology of polymer blends. The dynamics of phase separation and the mutual influence between thermodynamics and rheology are integrated in the text. The book provides an extensive list of references to scientific and patent literature. It is directed to engineers and scientists working on polymer blends in industrial or academic environments. In part 1 the author outlines the history of blending, its importance to the polymer industry, then briefly discusses the principles governing the development and processing of successful blends. Part 2 is dedicated to fundamental principles of polymer-polymer interaction and miscibility, to dynamic and equilibrium thermodynamics, and to principles of alloying. In Part 3 the flow behaviour of multiphase polymeric systems is considered with implications for polymer processing. The development of morphology as well as ultimate properties are briefly examined.

The use of computers in polymer processing brings many benefits, including an increase in productivity which otherwise could not be achieved. The main aim of this volume is to cover some recent advances made in various areas of polymer processing with specific attention paid to polymer modelling. A major emphasis is given to simulation of kinematics and dynamics of flow processes in various polymer processing operations. This volume should be helpful to those who are engaged in the research and development of polymer processing. The first section summarizes recent advances in modelling of various polymer processing operations. The second section describes some recent efforts in modelling of extrusion processes. The third section is concerned with the finite element simulation of thermoforming and blow molding processes. The fourth section deals with simulation of the injection molding of thermoplastics and rubber compounds.
