Abstract
To provide a hydrophobic linear polyrotaxane molecule which is soluble in an organic solvent, and a crosslinked polyrotaxane using the same. A hydrophobic linear polyrotaxane molecule has a cyclic molecule, a linear molecule including the cyclic molecule with piercing through the cyclic molecule, and blocking groups placed at both end terminals of the linear molecule to prevent the cyclic molecule from leaving from the linear molecule. The linear molecule is hydrophobic. The linear molecule is polycaprolactone and has a molecular weight ranging from 5,000 to 100,000. The cyclic molecule is α-cyclodextrin, β-cyclodextrin or γ-cyclodextrin. A crosslinked polyrotaxane is formed by combining the hydrophobic linear polyrotaxane molecule and a polymer through the cyclic molecule.
