Abstract (en)
[origin: DE19826135A1] The invention relates to grafted copolymers P with a defined core-shell morphology and a mean particle size (d50) of between 300 and 750 nm, containing, in relation to P, A) between 0,05 and 2.5 weight % of a stage A having a glass transition temperature of at least 25 DEG C on the basis of a vinyl aromatic monomer; B) between 9.8 and 30 weight % of a stage B having a glass transition temperature of at least 25 DEG C and a mean particle size (d50) of between 100 and 350 nm on the basis of a polymer made of a vinyl aromatic compound and several cross-linking agents; C) between 30 and 70 weight % of a stage C having a glass transition temperature of no more than 0 DEG C, on the basis of an alkyl acrylate; and D) between 20 and 60 weight % of a stage D having a glass transition temperature of at least 25 DEG C, on the basis of a vinyl aromatic monomer.
