Abstract

The present invention relates to thermoplastic moulding compositions containing (A) 20 to 80 parts by weight of a polydiorganosiloxane/polycarbonate block copolymer, (B) 70 to 5 parts by weight of a graft polymer in particle form and (C) 5 to 60 parts by weight of a rubber-free, thermoplastic vinyl polymer, the total of parts by weight of components (A)+(B)+(C) being in each case 100 parts by weight, and, if appropriate, other known additives.
