Temperature responsive property of slide-ring gels formed by crosslinking of polyrotaxane (PR), inclusion complex between alkylated α-cyclodextrin and polyethylene glycol, was studied from a viewpoint of substituents and their introducing ratio. Aqueous solutions of the alkylated PR show thermo-reversible sol-gel transition whose temperature strongly depends on the hydrophobic nature of substituents and substitution ratio. This property of the PR is reflected in the temperature dependence of volume and viscoelasticity of the slide-ring gels.
