    Abstract: The present disclosure relates to impact strength modifiers, the derivative products thereof, and the use thereof in producing two-component epoxy resin compositions. The disclosure in particular relates to amino group terminated impact strength modifiers prepared by reacting a polyurethane prepolymer having isocyanate groups, a primary diamine, and optionally at least one Michael acceptor. The two-component epoxy resin compositions thus formulated are characterized by a great increase in impact strength while retaining an acceptable tensile shear strength. The impact strength modifiers according to the disclosure and the epoxy resin compositions comprising same are in particular suitable for vehicle manufacturing.

    Abstract: 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 compositions. They are particularly suited for use in heat-curing epoxy resin adhesives. It has been found that such epoxy resin compositions 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.

    Abstract: A composition having at least one radically polymerisable monomer M; at least one radical former, at least one epoxide resin A including an average of more than one epoxide group per molecule, and at least one compound of formula (I). Such compositions are suitable as adhesives, sealants or coatings. Shortly after the application thereof, they have a high initial strength and, after further hardening at room temperature, they reach a high level of final strength.
