摘要： A thermoplastic molding material consists of from 10 to 90 parts by weight of a polycarbonate A and from 90 to 10 parts by weight of a graft copolymer B having a mean particle size of from 200 to 700 nm (d.sub.50 value of the integral mass distribution). The graft polymer B is formed from an elastomer (rubber) (b.sub.1), which accounts for from 10 to 80% by weight, and a grafted shell (b.sub.2), which accounts for from 90 to 20% by weight, the percentages in each case being based on (B).The elastomer (b.sub.1) is composed of from 50 to 99.9% by weight of an alkyl acrylate, where alkyl is of 1 to 8 carbon atoms, and from 0.1 to 5% by weight of a copolymerizable polyfunctional crosslinking monomer.The grafted shell (b.sub.2) is produced in three stages and contains, as graft monomers,(b.sub.2 a.sub.1) from 5 to 40% by weight of a monoethylenically unsaturated aromatic hydrocarbon of not more than 12 carbon atoms, in the first stage,(b.sub.2 a.sub.2) from 15 to 50% by weight of a mixture of a monoethylenically unsaturated aromatic hydrocarbon of not more than 12 carbon atoms and a copolymerizable ethylenically unsaturated monomer, in a weight ratio of from 90:10 to 60:40, in the second stage, and(b.sub.2 a.sub.3) from 10 to 85% by weight of an alkyl (meth)acrylate in the third stage, the percentages in each case being based on (b.sub.2).
