Abstract: There is provided a cured product of an epoxy resin composition, in which the compounding composition and the phase-separated structure of the epoxy resin composition are controlled so that the balance between rigidity and toughness of the cured product is superior compared with those of cured products of conventional epoxy resin compositions. A cured product of an epoxy resin composition, which has both superior rigidity and superior toughness compared with conventional materials can be produced by curing an epoxy resin composition comprising an epoxy resin, a polyrotaxane having graft-chain-modified cyclic molecules and a curing agent for the epoxy resin.

Abstract: An epoxy resin composition according to the present invention comprises an epoxy compound (A), a block copolymer (B) and a curing agent (C), wherein the block copolymer (B) is composed of a polymer block (a) comprising a (meth)acrylic polymer and a polymer block (b) comprising an acrylic polymer that is different from the polymer block (a), said epoxy resin composition having such a property that a cured resin product produced by curing the epoxy resin composition forms a microphase-separated structure. A cured product of the epoxy resin composition forms a highly ordered phase structure, and therefore has excellent toughness and stiffness.
