Toughened Epoxy Resin Composition with Excellent Interfacial Adhesion and Method for Manufacturing the Same

摘要

The present invention relates to a toughened epoxy resin composition having excellent interfacial adhesion and a method for producing the same.;An object of the present invention is to provide a toughened epoxy resin composition having excellent interfacial adhesion, a method for producing the same, and a cured product of the epoxy resin, and to improve the impact resistance of the resin in order to improve the brittleness property of the epoxy resin.;According to the present invention, the reactive polyether ester-based copolymer represented by the following chemical formula (1) is obtained by using the main component as an epoxy resin in an amount of 10 to 30% by weight per 100% by weight of the total amount of the epoxy resin and the reactive polyether ester-And dicyandiamide, which is a curing agent, is contained in an equivalent ratio to the above-mentioned epoxy resin.;Provided that m and n are integers and ranges from 100 to 200, x is 10, and R is (CH₂)₄O, (CH₂)₆O.
