In polymer science and technology, the advanced development of various new polymer materials with excellent properties and functions is desirable. For this purpose it is necesary to determine the exact relationship between physical properties and molecular structure-dynamics with powerful techniques. One such technique is solid state NMR. Recently, high resolution NMR studies of solids have been realized by using advanced pulse and mechanical techniques, which has resulted in a variety of structural and dynamical information on polymer systems. Solid state NMR has provided characteristic information which cannot be obtained by other spectroscopic methods. This book is divided into two parts. The first part covers the principles of NMR, important NMR parameters such as chemical shifts, relaxation times, dipolar interactions, quadrupolar interactions, pulse techniques and new NMR methods. In the second part, applications of NMR to a variety of polymer systems in the solid state are described. Features of this book: • Contains an up-to-date and comprehensive account of solid state NMR of polymers by leading researchers in the field • Provides a compilation of solid state NMR of polymers, which makes it an ideal reference book for both NMR researchers and general polymer scientists. This book will be of interest to the NMR community, and will be invaluable for both the beginner and the expert.

"Research on the dynamic properties and related molecular reorientation processes in polymer chains has attracted special attention in recent years. The solid-state nuclear magnetic resonance (SSNMR) is one of the most important complementary techniques in the scientific testing of macromolecules. When polymer molecules make reorientation motions, a fluctuating local magnetic field is generated. Thus, the shape of the resonance line emerges as a function of temperature and reveals the activation energy of the polymer chain"--

NMR spectroscopy has emerged as one of the most important methods for the solid-state characterisation of polymers. This report gives an overview of the methods and applications of NMR to relevant polymer problems with an emphasis on how NMR can be used for materials characterisation and to understand structure-property relationships in polymers. An additional indexed section containing several hundred abstracts from the Rapra Polymer Library database gives useful references for further reading.

Since the introduction of FT-NMR spectroscopy around five decades ago, NMR has achieved significant advances in hardware and methodologies, accompanied with the enhancement of spectral resolution and signal sensitivity. Rapid developments in the polymers field mean that accurate and quantitative characterization of polymer structures and dynamics is the keystone for precisely regulating and controlling the physical and chemical properties of the polymer. This book specifically focuses on NMR investigation of complex polymers for the polymer community as well as NMR spectroscopists, and will push the development of both fields. It covers the latest advances, for example high field DNP and ultrafast MAS methodologies, and show how these novel NMR methods characterize various synthetic and natural polymers.

A Practical Guide to Understanding the NMR of Polymers presents an introduction to the theory and practice of NMR, and includes sections on the fundamental principles of NMR and the applications to polymers. This book will help readers understand how these methods can be used to determine the chemical structure of polymers that influences the macroscopic properties. Solid state NMR methods are introduced to enable the readers to measure the structure of polymers on longer length scales. It is also shown how NMR is used to measure the molecular dynamics that can be related to the mechanical properties of polymers.
