Chapter 9 - Applications of high-resolution solid-state NMR spectroscopy to polymers

Abstract

This chapter discusses the increase in utility of solid state NMR in the study of polymer systems. This is largely because of the unique information that is available from the NMR measurements including the information relative to chemical structure, the molecular conformation, and packing in the solid state. Solid-state NMR spectroscopy has been used for two general classes of samples— the one that are insoluble such as crosslinked or intractable systems and the other for which solid-state NMR spectroscopy provides information about the nature of the solid state such as the conformation, crystallographic forms, and the morphological character of the solid. The interpretation of spectra from solid-state NMR spectroscopy is more complicated than the interpretation of solution NMR spectra. The utility of solid state NMR continues to grow. Many new applications particularly those based on motional differences of the phases are developing because experiments are easier to do with better spinners and decoupling methods.
