ABSTRACT:
Core/shell particles comprising a core comprising an elastomer having a T.sub.G value of <0.degree. C., onto which a shell of a crosslinked copolymer is grafted, where the proportion of the crosslinking component in the copolymer of the shell is from greater than 5 to 90% by weight, based on the total amount of the comonomers of the shell copolymer, are suitable as toughening agents for epoxy resins, with which they have good compatibility.
