Abstract: What is described is a polymer which is a polyurethane polymer having blocked isocyanate groups or a reaction product of said polyurethane polymer with at least one epoxy resin, where the polyurethane polymer having blocked isocyanate groups is an addition product formed from at least one polyisocyanate and at least one polyester polyol, wherein the isocyanate groups of the addition product have been blocked by reaction with at least one aromatic compound having at least one hydroxyl group. Such a polymer is suitable as an impact modifier in epoxy resin compositions, especially when they are used as adhesives or structural foams. The polymer improves the corrosion resistance and vertical expansion of the epoxy resin composition.

Abstract: An oligomeric condensation product can be obtained from at least one (hydroxymethyl)phenol of general formula (I), in which R1 is hydrogen or —CH3, R2 is —CH2OH, and R3 is hydrogen or —CH3, at least one polyamine, and optionally at least one phenol compound having two centers reactive by means of a reaction with the methylol groups of the (hydroxymethyl)phenol.
