    • The present invention aims to provide a method for producing a polyrotaxane which enables industrially advantageous production of a polyrotaxane with a high inclusion rate.
      The present invention relates to a method for producing a polyrotaxane that includes a cyclodextrin; a compound having a repeating structural unit represented by the following formula (1), and threading through a cavity of the cyclodextrin in a skewered manner to be included in the cyclodextrin; and capping groups individually placed at each end of a molecule of the compound having a repeating structural unit represented by the formula (1) to prevent the cyclodextrin from separating, the method comprising: a step 1 of mixing the compound having a repeating structural unit represented by the formula (1) and the cyclodextrin in an aqueous medium to prepare an aqueous dispersion of pseudopolyrotaxan particles in which the compound having a repeating structural unit represented by the formula (1) is included in a cavity of a cyclodextrin molecule in a skewered manner; and a step 2 of mixing a triazine compound represented by the formula (2), a compound having at least one tertiary amino group, the aqueous dispersion of pseudopolyrotaxane particles prepared in the step 1, and a capping agent to introduce capping groups individually at each end of a molecule of the compound having a repeating structural unit represented by the formula (1) in the pseudopolyrotaxane particles,



      wherein, in the formula (2), R 1 and R 2 are each independently a C1-C4 alkyl group or a C6-C8 aryl group, and X represents a halogen atom.
