Zusammenfassung: | Compositions containing A) a copolymer based on at least one 1,3-diene and at least one polar, ethylenically unsaturated comonomer, and B) a compound of the formula I in which m is 1 or 2, n is 2 to 6, R is the n-valent radical of an elastomeric prepolymer which is soluble or dispersable in epoxy resins, X and Y, independently of one another, are -O- or -NR -, where at least one of these groups must be -NR -, R is an m + 1-valent radical of a polyphenol or aminophenol, and R is hydrogen, C1-C6-alkyl or phenyl, or containing components A) and B) and an epoxy resin C) can be cured to give products of high peel strength and high tear propagation resistance. The curable compositions can be employed, for example, as structural adhesives. |
