Nuclear magnetic resonance (NMR) spectroscopy has proved to be of great significance in many aspects of polymer science. Because of the rapid expansion of this field, a review is felt to be justified at this time even though a number have appeared in recent years. (1-6) Earlier NMR studies have dealt with solid polymers, and the spectra obtained have been of the so-called "wide-line" type. In such spectra, as in the corresponding spectra of non-polymeric solids, analysis of the resonance lines, particularly if known as a function of temperature, can give information about the packing and motion of the polymer chains. (7-9) To such studies have more recently been added the measurement of the spin-lattice and spin-spin nuclear relaxation times, T1 and T2 (see below), in both solid state and solution, providing further insight into the motion and interaction of polymer chains. (10-21)

The present review will deal primarily with the structure and conformation of vinyl polymers, and will therefore (for reasons to be made clear in the next section) be confined to spectra of polymer solutions, since in general features providing such information cannot be resolved in solid state spectra.

The study of biopolymers has been a particularly active field of high resolution NMR spectroscopy very recently. Because of space limitations and because this area clearly deserves a review of its own, it will not be treated here.
