Abstract: A mixture, which contains a) 25 to 75% by weight of a block copolymer A, which contains at least one hard block S of vinyl aromatic monomers and one or more soft blocks BA of, in each case, 0 to 5% by weight of vinyl aromatic monomers and 95 to 100% by weight of dienes, the proportion by weight of the hard blocks S in the block copolymer A constituting 65 to 90% by weight; b) 5 to 25% by weight of a block copolymer B, which contains at least one hard block S of vinyl aromatic monomers and one or more copolymer blocks (B/S)B of, in each case, 20 to 60% by weight of vinyl aromatic monomers and 80 to 40% by weight of dienes, the proportion by weight of the hard blocks S in the block copolymer B constituting 25 to 70% by weight; c) 0 to 70% by weight of a block copolymer C, which is different from A and B, or polystyrene; and d) 0 to 6% by weight of a plasticizer D, the sum of the components A) to D) adding up to 100% by weight, as well as the use for transparent, thermoformed films or transparent injection-molded articles.
