Abstract
Graft copolymers (P1) contain, in any desired sequence, at least (P1.1) a hard segment having a glass transition temperature of at least 11.degree. C., which contains at least one vinylaromatic monomer as the monomer or as one of two or more monomers copolymerizable with one another and a crosslinker component comprising at least dihydrodicyclopentadienyl acrylate as a crosslinking agent having two or more functional groups of different reactivity and at least one crosslinking agent having two or more functional groups of the same reactivity, and (P1.2) a soft segment having a glass transition temperature of not more than 10.degree. C., which contains at least one acrylate as the monomer or as one of two or more monomers copolymerizable with one another, and blends and thermoplastic materials contain said graft copolymers.
