    Abstract: Mixture (A) comprises linear block copolymers of vinyl aromatic monomers and diene structural units, and the ratio of (I)/(II) amounts to 0.5-10. Mixture (A) comprises linear block copolymers of vinyl aromatic monomers and diene structural units of formula (S 1-B 1-S 2 (I) and B 2-S 3 (II)) and the ratio of (I)/(II) amounts to 0.5-10. S 1blocks of vinyl aromatic monomers with an average molecular mass of 40000-100000 g/mol; S 2, S 3blocks of vinyl aromatic monomers with an average molecular mass of 5000-20000 g/mol; and B 1, B 2one or more blocks of diene or copolymer blocks of diene and vinyl aromatic monomers with an average molecular mass of 15000-100000. Independent claims are also included for: (1) a mixture obtained by partial or complete hydrogenation of the linear block copolymers of vinyl aromatic monomers and diene structural units; and (2) the preparation of (A).
