Abstract: The present invention relates to mixtures comprising linear block copolymers made from vinylaromatic monomers and from dienes of the structure (I) S 1 -B 1 -S 2 and (II) S 3 -B 2 -S 4 , where S 1 is a block made from vinylaromatic monomers with number-average molar mass M n in the range from 40,000 to 100,000 g/mol, each of S 2 , S 3 and S 4 is a block made from vinylaromatic monomers with number-average molar mass M n in the range from 5,000 to 20,000 g/mol, each of B 1 and B 2 is a block made from dienes or a copolymer block made from dienes and from vinylaromatic monomers with numberaverage molar mass M n in the range from 15,000 to 40,000 g/mol, and the ratio of the block copolymers (I)/(II) is in the range from 0.6 to 2.

Abstract: A mixture which comprises from 5 to 50% by weight of a block copolymer A, which comprises one or more copolymer blocks (B/S)A each composed of from 65 to 95% by weight of vinylaromatic monomers and from 35 to 5% by weight of dienes and of a glass transition temperature TgA in the range from 40° to 90° C.; from 95 to 50% by weight of a block copolymer B, which comprises at least one hard block S composed of vinylaromatic monomers and comprises one or more copolymer blocks (B/S)B each composed of from 20 to 60% by weight of vinylaromatic monomers and from 80 to 40% by weight of dienes and of a glass transition temperature TgB in the range from −70° to 0° C.; from 0 to 45% by weight of polystyrene or of a block copolymer C other than A and B; and from 0 to 6% by weight of a plasticizer; and its use for production of shrink films.

Abstract: In a block copolymer (I) containing at least two hard blocks (S1, S2) prepared from a vinylaromatic monomer (M1) and, between them, at least one soft block (BS) prepared from M1 and a diene (M2), the proportion of hard blocks is over 40 wt.% of total (I). Independent claims are also included for the following: (a) mixtures of (I) and additional styrene polymers; and (b) preparation of (I) by sequential anionic polymerization, with at least polymerization of BS being in presence of a potassium salt.
