Abstract: The purpose of the present invention is to provide a method for manufacturing polyrotaxane that can produce polyrotaxane with a high inclusion rate using an industrially advantageous method. The present invention is a method for manufacturing polyrotaxane, the polyrotaxane having: cyclodextrin; a compound having repeating structural units expressed by formula (1) that penetrates and is trapped in a skewered form in the openings of the cyclodextrin; and a blocking group located on both ends of the compound having repeating structural units expressed by formula (1), the blocking group preventing removal of the cyclodextrin. The method has: a first step for mixing cyclodextrin and the compound having repeating structural units expressed by formula (1) in an aqueous solvent, and obtaining a pseudo-polyrotaxane aqueous dispersion containing pseudo-polyrotaxane particles where the compound having repeating structural units expressed by formula (1) is trapped in skewered form in the openings of the cyclodextrin molecule; and a second step where a triazine compound expressed by formula (2), a compound having at least one tertiary amino group, the pseudo-polyrotaxane aqueous dispersion obtained in the first step, and a blocking agent are mixed together and a blocking group is introduced to both ends of the compound having repeating structural units expressed by formula (1) in the pseudo-polyrotaxane. In formula (2), R1 and R2 each independently represent an alkyl group with 1 to 4 carbon atoms, or an aryl group with 6 to 8 carbon atoms, and X represents a halogen atom.
