    Abstract: The invention relates to a mixture, comprising a) 5 to 50 wt. % of a block copolymer (A), with one or more block copolymers (B/S)A, each made from 65 to 95 wt. % vinylaromatic monomers and 35 to 5 wt. % dienes with a glass transition temperature TgA in the range 40~ to 90 ~C, b) 95 to 50 wt. % of a block copolymer B, with at least one hard block (S) made from vinylaromatic monomers and one or more copolymer blocks (B/S)B, each made from 20 to 60 wt. % vinylaromatic monomers and 80 to 40 wt. % dienes and a glass temperature TgB in the range -70~ to 0 ~C, c) 0 to 45 wt. % of a block copolymer (C) different from (A) and (B), or polystyrol and d) 0 to 6 wt. % of a plastifier and the use thereof for the production of shrink films.
