in most of the applications where polymers are used, more than one phase is present. in addition to the polymer matrix, the second phase may be comprised of the same or a different polymer, or of some type of filler or fiber which is typically a solid or solid-like. typical applications of these materials include use in: structural composites; adhesives; chromatography; protective coatings; elastomers; and particle stabilization and separation. a brief review of the use of magnetic resonance of polymer molecules attached to solid surfaces is given with examples. liquid, solid (including wide-line and magic angle spinning), and two dimensional magnetic resonance experiments have all been performed on surface polymers the results suggest how magnetic resonance techniques can be used to probe the dynamics and structure of the polymer in composites, dispersions, surface treatments and the drying of coating.
