The invention relates to compositions comprising the following components a), b) and c), to a method for the production thereof and to the use thereof. In order to improve the fracture toughness of the cured epoxy resins, compositions comprising the following components a), b) and c) are proposed: a) -75 to 99.5% by weight of a polymer based on an epoxy compound, -0.5 to 25% by weight of at least one polyol, and-optionally additives b) -80 to 99% by weight of a curing agent suitable for curing the polymer based on an epoxy compound, -1 to 20% by weight of a polycaprolactone-polysiloxane-block copolymer, -optionally an accelerator, and-optionally additives, and c) -optionally an accelerator. |
