The invention relates to thermoplastic molding compounds which contain impact-modified styrene/nitrile monomer copolymers, to molded products and films produced therefrom and to the use thereof. The impact modifiers used are linear A-B-A tri-block copolymers from hard polymer blocks A and a soft polymer block B, preferably polymethylmethacrylate-block-polybutylacrylate-block-polymethylmethacrylate.
