    摘要： The present invention relates to a butadiene/acrylonitrile copolymer CTBN, modified by epoxy solid resin and terminated by carboxyl groups, the terminal epoxy groups thereof also having optionally been reacted. A polymer of this type is used in particular as an impact strength improving agent in epoxy resin compositions and has proven to be particularly advantageous for gluing on or of metal surfaces. It results in a significant reduction of the infiltration with corrosion, which in turn ensures a long-lived adhesive bond.

    摘要： The present invention relates to compositions which contain at least one epoxide adduct A having on average more than one epoxide group per molecule, at least one polymer B of the formula (I), at least one thixotropic agent C, based on a urea derivative in a nondiffusing carrier material, and at least one curing agent D for epoxy resins, which is activated by elevated temperature. This composition serves in particular as an adhesive and has an extremely high dynamic resistance to cleavage, in particular at low temperatures. The invention furthermore relates to impact strength modifiers terminated with epoxide groups and of the formula (I). It has been found that these novel impact strength modifiers result in a significant increase in impact strength in epoxy resin compositions, in particular in two-component epoxy resin compositions.

    摘要： The present invention relates to epoxy group-terminated polymers of the formula (I). Said epoxy group-terminated polymers are suited extremely well as impact resistance modifiers, particularly in epoxy resin compostions. They are particularly suited for use in heat-curing epoxy resin adhesives. It has been found that such epoxy resin compostions not only have excellent mechanical properties and high glass transition temperatures, but also above all improved impact resistance properties, both at room temperature and at low temperatures.
