Thermosetting reaction adhesives

Thermo-setting reaction adhesive as a mono-component system having storage stability, containing respectively at least

• a) one unsaturated backbone polymer on the basis of a non-cross-linked elastomer in a concentration of 5 to 90% by weight,
• b) one unsaturated polyester in a concentration of 5 to 90% by weight,
• c) one unsaturated cross-linking agent in a concentration of 0.1 to 50% by weight, and
• d) one setting catalyst which provides radicals in a concentration of 0.2 to 6% by weight and which is selected from at least one of tert-butylperbenzoate;
• tert-butylpermaleate;
• bis(tert-butylperoxyisopropyl)benzene;
• 1,1-di(tert-butylperoxy)-3,3,5-trimethyl-cyclohexane;
• n-butyl-4,4-di(tert-butylperoxy(valerate;
• ethyl-3,3-di(tert-butylperoxy)butyrate;
• 3,3,6,6,9,9-hexamethyl-1,2,4,5-tetraoxa-cyclohexane;
• 2,2-bis(tert-butylperoxy)butane;
