This book describes the properties of single polymer molecules and polymeric materials and the methods how to characterize them. Molar masses, molar mass distributions and branching structure are discussed in detail. These properties are decisive for a deeper understanding of structure/properties relationships of polymeric materials. This book therefore describes and discusses them in detail. The mechanical behavior as a function of time and temperature is a key subject of the book. The authors present it on the basis of many original results they have obtained in their long research careers. They present the temperature dependence of mechanical properties of various polymeric materials in a wide temperature range: from cryogenic temperatures to the melt. Besides an extensive data collection on the transitions of various different polymeric materials, they also carefully present the physical explanations of the observed phenomena. Glass transition and melting temperatures are discussed, particularly, with their relevance for applications. A comprehensive part of the book deals with properties of polymers in the molten state and their decisive influence on the processing of the materials. The book presents and discusses viscous and elastic properties in detail as a function of molar mass, polydispersity, and branching. This book addresses students of polymer and materials science, as well as other natural sciences. Besides this educational value, it will also serve as a valuable monograph for everyone dealing with polymers and polymeric materials, from research, over development, to applications.

Volume 1 presents first fundamental principles of the rheology of polymeric fluid including kinematics and stresses of a deformable body, the continuum theory for the viscoelasticity of flexible homogeneous polymeric liquids, the molecular theory for the viscoelasticity of flexible homogeneous polymeric liquids, and the experimental methods for the measurement of the rheological properties of poylmeric liquids. The materials presented are intended to set a stage for the subsequent chapters by introducing the basic concepts and principles of rheology, from both phenomenological and molecular perspectives, ofstructurally simple flexible and homogeneous polymeric liquids. Next, this volume presents the rheological behavior of structurally complex polymeric materials including miscible polymer blends, block copolymers, liquid-crystalline polymers, thermoplastic polyurethanes, immiscible polymer blends, perticulare-filled polymers, organoclay nanocomposites, molten polymers with dissolved gas, and thermosts.

"This new edition introduces the field of polymers, balancing chemistry, physics, and engineering applications. It updates a classic text used in introductory polymer courses, but has not been updated since 1993. This revised and updated edition focuses on new technologies that use polymers, new feedstocks, polymers derived from biological sources, new polymerization strategies, and analysis of polymers. Further, the third edition includes new homework problems and examples. With the updates mentioned, the book now includes the latest concepts while also remaining friendly to students new to the field"--

This book is the first to introduce a mesoscale polymer simulation system called OCTA. With its name derived from "Open Computational Tool for Advanced material technology," OCTA is a unique software product, available without charge, that was developed in a project funded by Japanese government. OCTA contains a series of simulation programs focused on mesoscale simulation of the soft matter COGNAC, SUSHI, PASTA, NAPLES, MUFFIN, and KAPSEL. When mesoscale polymer simulation is performed, one may encounter many difficulties that this book will help to overcome. The book not only introduces the theoretical background and functions of each simulation engine, it also provides many examples of the practical applications of the OCTA system. Those examples include predicting mechanical properties of plastic and rubber, morphology formation of polymer blends and composites, the micelle structure of surfactants, and optical properties of polymer films. This volume is strongly recommended as a valuable resource for both academic and industrial researchers who work in polymer simulation.

The rheology of polymer melts plays an important role today in industry and academia. Although several textbooks on this subject are available, with very few exceptions they cover homogeneous products only. This book is unique in that it focuses on heterogeneous systems such as particle-filled materials and polymer blends, which are highly important in the world market. It deals with similarities and differences of the flow properties of these two classes of material, providing both a fundamental and a practical understanding. Key points of the book are the viscous and elastic properties of engineering polymers filled with functional particles and the influence of nanoparticles on rheological properties. Two key aspects of rheological measurements are discussed: the influence of heterogeneous structures on the flow of materials important for processing and the use of rheological means to get an insight into morphological features. Both approaches are applied to particle-filled melts and to polymer blends. In the latter case it is shown in detail in which way the deformation of droplets formed by the dispersed phase can be affected by outer deformation, particularly in elongation.

This book provides a comprehensive introduction to the study of polymers. Special emphasis is given to the characteristics that set polymers apart from small molecules, as studied in classic chemistry courses. The various branches of polymer science are introduced and discussed in a systematic manner, starting from basic chemical structures, continuing through supermolecular organization and physical properties. Specific examples are used throughout to illustrate how end usage relates to the principles under discussion. A series of chapters is devoted to case studies describing the principal classes of synthetic polymers. Content includes: - Polymerization - Characterization of Polymers - Rheological Description of Polymer Melts - Structural Development - Properties - Compounding and Extrusion Processes - Molding processes - Additional Methods of Manufacture - Commodity Polymers - Engineering Thermoplastics - Neat Stuff
