Abstract

AbstractThis article presents the basic principles of nuclear magnetic resonance (NMR) and the application of NMR techniques to polymer problems. This includes one‐dimensional NMR studies of molecular motions and dynamic order, studies of viscoelastic polymers by two‐dimensional NMR spectroscopy, and NMR imaging methods. The emphasis is on studies of viscoelastic polymers for which NMR can provide information on such important areas as the chain dynamics in elastomers, the local structure, residual couplings (induced by chemical cross‐links and topological constraints), dynamic order parameters, internuclear distances, intermolecular interactions (which are important for instance for the miscibility), the effects of fillers on molecular motions, and segmental orientation under mechanical stress and others.
