Modified epoxide resins Compositions containing A) a copolymer based on at least one 1,3-dieneand at least one polar, ethylenically unsaturated comonomer and B) a com-pound of the formula I <IMG> (I) in which m is 1 or 2, n is Z to 6, R1 is the n-valent radical of an elastomeric prepolymer which is soluble or dispersible in epoxide resins, X and Y independently of one another are -O- or -NR3-, it being necessary for one of these groups to be -NR3-, R2 is an m+1-valent radical of a polyphenol or aminophenol and R3 is hydrogen, C1-C6alkyl or phenyl, are described. Compounds containing the components A) and B) as well as an epoxide resin C) are also described. The cured products are distinguished by a high peel strength and high resistance to crack propagation. The curable compositions can be employed, for example, as structural adhesives.
