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.
根据本发明,环氧树脂组合物由环氧化合物(A)、嵌段共聚物(B)和固化剂(C)组成,其中嵌段共聚物(B)由由(甲基)丙烯酸聚合物组成的聚合物嵌段(a)和由与聚合物嵌段(a)不同的丙烯酸聚合物组成的聚合物嵌段(b)组成,所述环氧树脂组合物具有这样的特性,即通过固化环氧树脂组合物产生的固化树脂产品形成微相分离结构。环氧树脂组合物的固化产物形成高度有序的相结构,因此具有极佳的韧性和刚度。
