The structural characterization for five currently used prosthetic‐orthotic polymers, determined by proton ( 1 H) nuclear magnetic resonance spectroscopy, showed residual unsaturation, CC groups, in all materials, ranging from 1.7 to 15%. The determination of residual unsaturation by 1 H‐NMR spectroscopy in polymers contributes information that may be useful for: (1) quality control of batches of materials. and (2) the development of standards, test methods necessary to evaluate the effects of environmental influences associated with long‐term clinical service. Materials selected for current usage were: Durr‐Plex (polyethylene terephthalate), polypropylene, Subortholen (polyethylene), Surlyn (ethylene methacrylate ionomer), and Uvex (cellulose acetate butyrate). © 1996 John Wiley & Sons, Inc.
