摘要：Graft copolymers (P1) having an average particle size of from 40 to 2000 nmcontain at least (P1.1) a soft segment having a glass transition temperature of not morethan 10° C. as a grafting base, which segment contains at least one acrylate as themonomer or as one of two or more monomers copolymerizable with one another, and atleast one crosslinking agent, and (P1.2) a hard segment having a glass transitiontemperature of at least 11° C. as a graft layer, which segment contains at least onevinylaromatic monomer as one of two or more monomers copolymerizable with oneanother, that region of the subsequent graft layer which is adjacent to the grafting baseP1.1 comprising at least one vinylaromatic monomer and the region facing away from thegrafting base comprising at least one vinylaromatic monomer with at least one monomercopolymerizable therewith, and blends and thermoplastic materials contain these graftcopolymers.
