Patent ID: 8575269

Claim:
A mixture comprising a) at least 30% by weight of a copolymer or block copolymer A comprising one or more copolymer blocks (B/S) A which are respectively composed of from 65 to 95% by weight of vinylaromatic monomers and of from 35 to 5% by weight of dienes, and whose glass transition temperature Tg A is in the range from 40° to 90° C., b) at least 20% by weight of a block copolymer B comprising at least one hard block S which is composed of vinylaromatic monomers, and comprising one or more copolymer blocks (B/S) B which are respectively composed of from 20 to 60% by weight of vinylaromatic monomers and of from 80 to 40% by weight of dienes, and whose glass transition temperature Tg B is in the range from −70° to 0° C., c) from 30 to 40% by weight of polystyrene C, d) at least 5% by weight of a block copolymer D comprising at least one copolymer block (B/S) A which is respectively composed of from 65 to 95% by weight of vinylaromatic monomers and of from 35 to 5% by weight of dienes, and whose glass transition temperature Tg A is in the range from 40° to 90° C., and comprising at least one diene block B or copolymer block (B/S) B which is respectively composed of from 1 to 60% by weight of vinylaromatic monomers and of from 99 to 40% by weight of dienes, and whose glass transition temperature Tg B is in the range from −100° to 0° C., wherein component d) is (S/B) A -(S/B) B or (S/B) A -B-S, and e) from 0 to 6% by weight of a plastifying agent E.
