    Abstract: The present invention aims to provide an industrially advantageous method for producing an aqueous dispersion of pseudopolyrotaxane enabling to produce an aqueous dispersion of pseudopolyrotaxane having good fluidity and excellent dispersion stability of the pseudopolyrotaxane particles therein. The present invention relates to a method for producing an aqueous dispersion of pseudopolyrotaxane. The method includes: a mixing step of a dissolving polyethylene glycol and a cyclodextrin in an aqueous medium to prepare a mixed solution; and a cooling step of continuously or intermittently cooling the mixed solution in a state of flux to precipitate pseudopolyrotaxane particles. The pseudopolyrotaxane particles contain the polyethylene glycol which is included in the cavities of the cyclodextrin molecules in a skewered manner.

    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.
