Abstract
A polyrotaxane which has enhanced solubility and is soluble in various solvents, 2) a polyrotaxane which is reversibly responsive to an external stimulus, 3) a chemically crosslinked polyrotaxane which has a high Young's modulus and a high elongation and has a high transmittance, and/or 4) a chemically crosslinked polyrotaxane which is reversibly responsive to an external stimulus; and/or a material containing any of these; and/or processes for producing these. The polyrotaxanes each comprises: a pseudo-polyrotaxane having a structure constituted of cyclic molecules and a linear molecule with which the holes of the cyclic molecules are pierced to form a clathrate; and a blocking group disposed at each end of the pseudo-polyrotaxane so as to prevent the cyclic molecules from leaving. The cyclic molecules have a functional group represented by the following formula (I) and at least one functional group selected among functional groups represented by the following formulae (II-1) to (II-6).
