Patent ID: 8759445

Claim:
A mixture comprising a) from 5 to 95% by weight of a 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 Tg A in the range from 40° to 90° C., b) from 95 to 5% by weight of a block copolymer B which comprises hard blocks S composed of from 95 to 100% by weight of vinylaromatic monomers and of from 0 to 5% by weight of dienes, and comprises one or more copolymer blocks (B/S) A each composed of from 65 to 95% by weight of vinylaromatic monomers and of from 35 to 5% by weight of dienes and of a glass transition temperature Tg A in the range from 40° to 90° C., and comprises one or more copolymer blocks (B/S) B each composed of from 20 to 60% by weight of vinylaromatic monomers and of from 80 to 40% by weight of dienes and of a glass transition temperature Tg B in the range from −80° to 0° C., and wherein the hard blocks S of the block copolymer B occur terminally (S e ) or between (S i ) the copolymer blocks (B/S) A and (B/S) B and wherein the hard blocks S of the block copolymer B have a number average molar mass M n in the range from 5000 to 30,000 g/mol, c) from 0 to 45% by weight of thermoplastic polymers C other than A and B, and d) from 0 to 6% by weight of processing aids D, where the entirety of A to D gives 100% by weight.
