Abstract
Provided are a polyrotaxane capable of using an aqueous solvent in a fabricating process although it has hydrophobicity, an aqueous composition having the polyrotaxane, a crosslinked body comprising the polyrotaxane, etc. The polyrotaxane comprises blocking groups located at both ends of a pseudo-polyrotaxane having cyclic molecules and a linear molecule which pierces the cavities of the cyclic molecules in a skewered manner to form a clathrate therewith so as not to detach the cyclic molecules, wherein the cyclic molecules have a group represented by Formula I, a group represented by Formula II and a group represented by Formula III. Incidentally, M represents, for example, a group derived from ring-opening polymerization of ε-caprolactone or the like, A represents a hydroxy group or the like, B represents a —COOH group or the like, and C represents A and/or B:-M-A  Formula I;-M-B  Formula II; and—C  Formula III.
