Abstract

Novel impact strength modifiers which are obtained by reaction of amphiphilic block copolymers. These impact strength modifiers are suitable in particular for use in heat-curing epoxy resin adhesives. In particular, combinations of different impact strength modifiers are also suitable for use in heat-curing epoxy resin adhesives. Also disclosed are methods of bonding heat-stable substrates.
