title: Thermoreversible sol-gel transition of an aqueous solution of polyrotaxane composed of highly methylated alpha-cyclodextrin and polyethylene glycol.
abstract: Novel thermo-gelling aqueous solution systems are developed with a polyrotaxane, consisting of methylated alpha-cyclodextrin and polyethylene glycol, based on the slide-ring properties of the macrocycles along the linear chain.
