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.

Best known for their use as bulk materials, polymers when used in small amounts as rheology modifiers can convert simple fluids to high-performance materials. Such additives have found use in paints and coatings, fuels and lubricating oils, cosmetics and personal care products, and food. This 20-chapter book presents a strong mix of industrial and academic contributions that cover rheological concepts, gels and latices, associating polymers, polymer-polymer and polymer-solvent interactions, and deformation-related orientations.

Constitutive Equations for Polymer Melts and Solutions presents a description of important constitutive equations for stress and birefringence in polymer melts, as well as in dilute and concentrated solutions of flexible and rigid polymers, and in liquid crystalline materials. The book serves as an introduction and guide to constitutive equations, and to molecular and phenomenological theories of polymer motion and flow. The chapters in the text discuss topics on the flow phenomena commonly associated with viscoelasticity; fundamental elementary models for understanding the rheology of melts, solutions of flexible polymers, and advanced constitutive equations; melts and concentrated solutions of flexible polymer; and the rheological properties of real liquid crystal polymers. Chemical engineers and physicists will find the text very useful.

One of the most important factors in chemical enhanced oil recovery (EOR) is mobility control, for which partially hydrolyzed polyacrylamide (HPAM) and other polymers are extensively used. With the recent surge of interest in polymer flooding, improved polymer products are manufactured, whose properties may be different from the similar polymers used during the earlier period of active chemical EOR applications. Also, as polymers are used for more complex and a wider range of reservoir conditions than applied before, new needs arise for more data on the flow properties. Therefore, an accurate description of the polymer viscosity is needed to design and make performance predictions with confidence, to satisfy those new demands. The objective of this study is to estimate steady shear viscosity of polymer solution under various reservoir and process conditions accurately, based on the laboratory viscosity measurements. For this purpose, empirical equations for polymer viscosity were developed in terms of different variables that affect polymer viscosity. Rheological properties of the EOR polymer solutions depend on the various factors such as polymer's molecular properties and concentration, salinity, hardness, shear rate and temperature. Therefore, rheological measurements with commonly employed EOR polymers under various conditions were made and the effect of these factors on polymer viscosity was quantified. Also, the parameters in the rheological models that correlate polymer viscosity with these variables were determined and used to develop a polymer database. The rheological measurements have been made to characterize the steady shear viscosity of EOR polymers (two kinds of HPAM polymers and a co-polymer of acrylamido-methyl-propane sulfonate (AMPS)) as a function of the factors mentioned above. In addition to the steady shear viscosities, the oscillatory rheological properties have also been measured to better define the polymer's viscoelastic behavior during flow in porous media. In view of the recent EOR applications to recover viscous oils and to offshore fields, the data were obtained for wider ranges of the polymer molecular weight and concentration, and salinity than those reported in the literature. The comprehensive compilation of the rheological data for currently available EOR polymers presented here will be useful not only for the polymer flooding and the use of polymer for surfactant-polymer and alkaline-surfactant-polymer flooding, but also for other oil industry applications such as the drilling fluid design.
