## Abstract **Summary:** Supramolecular hydrogels have been prepared on the basis of polymer inclusion complex (PIC) formation between poly(ethylene glycol) (PEG)‐modified chitosans and α‐cyclodextrin (α‐CD). A series of PEG‐modified chitosans were synthesized by coupling reactions between chitosan
## Abstract New hydrophilic networks combining poly(ethylene glycol) (PEG) and __β__‐cyclodextrin (__β__‐CD) have been prepared. Both components are linked by reacting PEG chains previously end‐capped with isocyanate groups and __β__‐CD, forming urethane links. Networks of molar compositions (__β__
