Nmr Of Polymers

Based on the authors ́ extensive experimental experience, NMR Spectroscopy of Polymers explains the practical use of NMR spectroscopy in polymer chemistry.

NMR has made important contributions to our understanding of structure–property relationships in polymers. This book provides an up-to-date and comprehensive overview of the fundamentals of NMR, with applications of multidimensional NMR and the new solution and solid-state methods in polymer science. NMR of Polymers is written by leading authorities for graduate students and professionals in academia and industry. Provides comprehensive overview of NMR in Polymer Science Covers multidimensional NMR Includes new solution and solid state methods Addresses chain conformation and dynamics

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.

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.

Solution-state NMR spectroscopy is generally regarded as the premier technique to characterise polymer structure. This report provides a timely review of the developments in the NMR of polymers in solution in the past few years. An additional indexed section containing several hundred abstracts from the Polymer Library gives useful references for further reading.

In the time since this book was written, the application of NMR in the study of polymers has continued to develop rapidly. The main trends of the work have remained as before, namely, the study of the structure of polymers, molecular motion in them, and chemical conversions of high-molecular-weight substances. How ever, as a result of the refinement of experimental techniques and development of the theory, new progress has been achieved, par ticularly in the NMR spectroscopy of polymer solutions. We therefore decided that it was worthwhile to provide an ad ditionallist of literature, covering papers published in 1965, 1966, and the beginning of 1967. By using the bibliographic directory appended to the list, the reader can readily find references to the latest literature for all sections of the book. I. Ya. Slonim A. N. Lyubimov v Preface to the Russian Edition The aim of this book is mainly to answer the questions which inevitably arise for a chemist who wishes to use NMR in his work on polymers.

R.N.IBBETT This book provides a source of information on all major aspects of NMR spectroscopy of synthetic polymers. It represents a deliberate attempt to pull together the numerous strands of the subject in a single comprehensive volume, designed to be readable at every scientific level. It is intended that the book will be of use to the vast majority of polymer scientists and NMR spec troscopists alike. Readers new to NMR will find extensive information within the book on the available techniques, allowing full exploration of the many polymer science applications. Readers already established within a branch of NMR will find the book an excellent guide to the practical study of polymers and the inter pretation of experimental data. Readers who have specialised in polymer NMR will find the book a valuable dictionary of proven methodologies, as well as a guide to the very latest developments in the subject. Workers from all of the main branches of polymer NMR have been invited to contribute. Each chapter therefore contains information relating to a parti cular investigative topic, indentified mainly on the basis of technique. The book is loosely divided between solution and solid-state domains, although the numerous interconnections confirm that these two domains are parts of the same continuum. Basic principles are explained within each chapter, combined with discussions of experimental theory and applications. Examples of polymer investigations are covered generously and in many chapters there are discussions of the most recent theoretical and experimental developments.

Describes both high resolution solution and solid state techniques; presents applications to synthetic and biological polymers; demonstrates the connection between microstructures, conformations, and NMR spectra of polymers. Annotation copyrighted by Book News, Inc., Portland, OR

The chapters in this collection are from papers which were presented at a symposium on solid-state NMR of polymers. A two-part program on available NMR techniques applicable to solid polymer analysis was presented at the 3rd Chemical Congress of North American held in Toronto, Ontario, June 5-10,1988. The program was sponsored by the Division of Polymer Chemistry with support provided by the Division, its Industrial Sponsors, and the Donors of the Petroleum Research Fund administered by the American Chemical Society. Co-organizers included Professor Colin Fyfe of the University of British Columbia (Vancouver, Canada), Professor Hans Spiess of the Max Planck Institut fur Polymerforschung (Mainz, West Germany), and myself. The full-day tutorial, which was free to registered attendees, covered the range of topics. The purpose of the tutorial was to provide a basic introduction to the field so that newcomers to its present and future applications could develop sufficient understanding to learn effectively from the subsequent symposium. The first talk attempted to give listeners a feel for the way a novice spectroscopist can learn to use the various NMR techniques to explore his own areas of interest. Simple experiments can provide unique information about solid polymers that can be useful in interpreting synthetic results and in relating solid-state conformation, morphology and molecular motion to physical properties.
