Completely revised and updated, the fourth edition of this classic text continues to offer the reader a thorough understanding of viscoelastic behavior, essential for the proper utilization of polymers.
Explains principles, corresponding equations, and experimental methods with supporting real-life applications
Adds coverage of measurement techniques (nano-indentation, atomic force microscopy (AFM), and diffusing wave spectroscopy (DWS)), biopolymer viscoelasticity, and the relationship between mechanical polymer properties and viscoelastic functions
Has two new ections to address modern areas of viscoelastic measurement: large amplitude oscillatory shear (LAOS) and microrheology
Includes problems in the text and an Instructor's Manual (including solutions) available for adopting professors
Prior edition reviews: "The book is clear written and...[is] appropriate for students in introductory undergraduate courses and for others wanting introduction to the fundamentals of the subject." (CHOICE, December 2005); "This book is invariably well written, logically organized and easy to follow...I highly recommend this book to anyone studying polymer viscoelasticity." (Polymer News, December 2005)
Autorentext
MONTGOMERY T. SHAW, PhD, is Emeritus Distinguished Professor of Chemical Engineering at the University of Connecticut. Among his books are the prior edition of Introduction to Polymer Viscoelasticity and Introduction to Polymer Rheology, both published by Wiley. WILLIAM J. MACKNIGHT, 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 Introduction to Polymer Viscoelasticity, all published by Wiley.
Klappentext
The revised fourth edition of the text that offers a thorough understanding of viscoelastic behavior, essential for the proper utilization of polymers The thoroughly revised and updated fourth edition of Introduction to Polymer Viscoelasticity 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. 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:
