<p><b>MONTGOMERY T. SHAW,</b> PhD, is Emeritus Distinguished Professor of Chemical Engineering at the University of Connecticut. Among his books are the prior edition of <i>Introduction to Polymer Viscoelasticity</i> and <i>Introduction to Polymer Rheology,</i> both published by Wiley. <p><b>WILLIAM J. MACKNIGHT,</b> PhD, is a Professor Emeritus at the University of Massachusetts Amherst, where he was formerly the co-Principal Investigator for the Center for UMass/Industry Research on Polymers (CUMIRP). He has been a co-author for each edition of <i>Introduction to Polymer Viscoelasticity,</i> all published by Wiley.
<p><b>The revised fourth edition of the text that offers a thorough understanding of viscoelastic behavior, essential for the proper utilization of polymers</b> <p>The thoroughly revised and updated fourth edition of <i>Introduction to Polymer Viscoelasticity</i> is the classic resource on the topic of molecular viscoelasticity. This important text bridges the gap between primers on polymer science and advanced research-level monographs. The authors assume a molecular, rather than a mechanical approach, and provide a strong grounding in the fundamental concepts, detailed derivations, and particular attention to assumptions, simplifications, and limitations. <p>Revisions to the updated fourth edition feature the inclusion of new measurement techniques, coverage of biopolymer viscoelasticity, and a vital discussion of the relationship between mechanical polymer properties and viscoelastic functions. In addition, the text contains two entirely new sections that address modern areas of viscoelastic measurement: large amplitude oscillatory shear (LAOS) and microrheology. The authors explain principles, corresponding equations, and experimental methods with supporting real-life applications and the text has supporting data available with a supplementary website. This important resource: <ul> <li> Offers a completely revised and updated guide to molecular viscoelasticity</li> <li> Includes coverage of measurement techniques (nano-indentation, atomic force microscopy (AFM), and diffusing wave spectroscopy (DWS)), biopolymer viscoelasticity</li> <li> Explores the relationship between mechanical polymer properties and viscoelastic functions</li> <li> Offers two new sections that address modern areas of viscoelastic measurement: large amplitude oscillatory shear (LAOS) and microrheology</li> </ul> <p>Written for polymer and materials scientists, chemical engineers, physical chemists, product design engineers, mechanical engineers, and students, <i>Introduction to Polymer Viscoelasticity</i> is the go-to resource for understanding the most current research and developments in the field.
