抄録

Thermoreversible hydrogels of the aqueous solutions of polyrotaxanes composed of polyethylene glycol and methylated α-CDs were investigated by DSC, X-ray diffraction, and rheological measurements. With increasing temperature, these aqueous solutions show sol to gel transition since hydrophobic interaction among α-CDs leads to aggregation of freely movable α-CDs on a PEG chain. These solutions have several kinds of gel formation mechanisms which strongly depend on the substitution ratio of methyl groups.
