Abstract

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.
