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.
