    摘要： The invention relates to compositions containing at least one epoxide adduct A that comprises an average of more than one epoxide group per molecule, at least one polymer B of formula (I), at least one thixotropic agent C based on a urea derivative in a non-diffusing carrier material, and at least one hardener D for epoxy resins, which is activated at an increased temperature. Said composition is used especially as an adhesive and is provided with an extraordinarily high impact peel working value, especially at low temperatures. The invention further relates to epoxide group-terminal impact strength modifiers of formula (I), which significantly increase the impact resistance in epoxy resin compositions, particularly two-component epoxy resin compositions.
