Abstract
The present invention relates to mixtures comprising linear block copolymers made from vinylaromatic monomers and from dienes of the structure (I) S-B-Sand (II) S-B-S, where Sis a block made from vinylaromatic monomers with number-average molar mass Min the range from 40,000 to 100,000 g/mol, each of S, Sand Sis a block made from vinylaromatic monomers with number-average molar mass Min the range from 5,000 to 20,000 g/mol, each of Band Bis a block made from dienes or a copolymer block made from dienes and from vinylaromatic monomers with numberaverage molar mass Min 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.
