MODIFIED HYDROPHILIC POLYROTAXANE AND CROSS-LINKED POLYROTAXANE

摘要

[PROBLEMS] To provide a modified hydrophilic polyrotaxane which is soluble in water or an aqueous solvent, a cross-linked polyrotaxane produced using the modified hydrophilic polyrotaxane, and a solvent for dissolving the modified hydrophilic polyrotaxane therein. [MEANS FOR SOLVING PROBLEMS] A modified hydrophilic polyrotaxane having a cyclic molecule, a linear molecule which includes the cyclic molecule with piercing through the cyclic molecule, and capping groups which are placed at both end termini of the linear molecule and serve to prevent the cyclic molecule from leaving from the linear molecule. The cyclic molecule is cyclodextrin, and each of all or some of the hydroxyl groups in the cyclodextrin is modified with a hydrophilic modification group. A cross-linked polyrotaxane comprising the modified hydrophilic polyrotaxane and a polymer linked through a cyclic molecule. A solvate for dissolving the modified hydrophilic polyrotaxane therein comprising water, an aqueous solvent or a combination thereof.
