    Abstract: The present invention provides a material of high toughness that could not have been provided by an epoxy resin alone. The present invention provides a crosslinking composition having (A) one or more polyrotaxanes in which end-capping groups which prevent dissociation of the linear group are situated at both ends of a pseudo-polyrotaxane formed by inclusion of a linear molecule in the opening of a cyclic molecule by being threaded therethrough, the polyrotaxane having on the cyclic molecule a functional group that is capable of reacting with the oxirane group and/or the oxetane group, the functional group being one or more selected from the group consisting of carboxylic acid groups, carboxylate groups, primary amine groups, secondary amino groups, tertiary amino groups, phenol groups, the oxirane group, and the oxetane group, and (B) a compound having two or more oxirane groups and/or oxetane groups; and a crosslinked product employing the composition.

    Abstract: 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.
