A new hydrogel that combines poly(ethylene glycol) and β‐cyclodextrin has been synthesized. Both components are linked by using a diisocyanate (HDMI), first by end‐capping the poly(ethylene glycol) with isocyanate groups an then reacting it with β‐cyclodextrin, forming urethane links. Hydrogels of molar compositions (β‐cyclodextrin/poly(ethylene glycol)) ranging from 1/4 to 1/14 have been synthesized. These hydrogels swell quickly and their water contents depend upon temperature. The gels are temperature resistant and show an elastomeric behavior. © 2006 Wiley Periodicals, Inc. J Appl Polym Sci 102: 1162–1166, 2006
