Solid‐state nuclear magnetic resonance (NMR) techniques were used to characterize cyclomaltoheptaose (β‐cyclodextrin, β‐CD) polymers. These insoluble materials have been investigated by cross‐polarization magic angle spinning with dipolar decoupling (CP/MAS), magic angle spinning without dipolar decoupling (MAS), and high‐resolution magic angle spinning with gradients (HRMAS). These NMR spectra allow the assignment of the principal 1 H and 13 C signals. The presence of two distinct components (cross‐linked β‐CD and polymerized epichlorohydrin) in the materials was clearly demonstrated. These polymers were used as sorbents and the resulting NMR spectra are presented and discussed. © 2000 John Wiley & Sons, Inc. J Appl Polym Sci 75: 1288–1295, 2000
