    摘要: 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.

    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.
