Abstract

The properties of solid polymers are determined to a large extent by the structure, order, and dynamics of the molecules which make up the polymers on a molecular scale as well as by the morphological domain structure involving the size and type of crystalline, amorphous and interfacial phases. Solid state NMR spectroscopy is a method particularly suited to the investigation of the properties of individual molecules since their resonance frequency depends on the structure and on the orientation of a molecular segment in the magnetic field. In addition, morphological aspects can be studied by following the spin diffusion between individual phases. This review covers NMR techniques devised recently to address such polymer specific questions.
