Transport in cellulose gels has been studied with ethylene glycol and crown ether (15-5) as "probes" using an NMR spin-echo technique. The cellulose content was varied in range 20-5570 (w/w). The retardation of diffusion was found to be adequately described by simple first-order expressions in conce
