It was found that water-repellent thermoplastic moulding compositions, which comprise a) from 66 to 72% by weight of one or more styrene-acrylonitrile copolymers as component A, b) from 25 to 35% by weight of one or more polyacrylate rubbers as component B, c) from 1 to 5% by weight of one or more fluorine-containing polymer components C, selected from the group of polyvinyliden-difluoride and polyvinyliden-tetrafluoride, d) from 0.05 to 6% by weight of one or more further additives, which are different from C, as component D, where each of the % by weight values is based on the total weight of components A to D and these give a total of 100% by weight, have good replication properties and lead to highly water-repellent surfaces.

Graft copolymers are prepared by anionic polymerization which comprises reacting polymers (A) having at least one anionic chain end with polymers (B) which contain at least one nitrile group, in the presence of a solvent.
