ABSTRACT Compositions based on epoxy resins are produced by reacting in a first step an epoxide prepolymer with a butadiene-acrylonitrile copolymer. In a second step, the product obtained in the first step is reacted with a liquid diamine which is reactive at low temperature. In a third step, the product obtained in the second step is reacted with an epoxide prepolymer in the presence of a second diamine. The second and third step can be combined. 35,335-F
