Abstract
Mixtures comprising linear block copolymers composed of vinylaromatic monomers and dienes of the structure (I) S-B-Sand (II) B-S, where Sis a block composed of vinylaromatic monomers whose number-average molar mass Mis in the range from 40 000 to 100 000 g/mol, each of Sand Sis a block composed of vinylaromatic monomers whose number-average molar mass Mis in the range from 5000 to 20 000 g/mol, each of Band Bis one or more blocks composed of dienes or is copolymer blocks composed of dienes and vinylaromatic monomers whose number-average molar mass Mis in the range from 15 000 to 100 000 g/mol, and the ratio of block copolymers (I)/(II) is in the range from 0.5 to 10, and their use for impact-modification of blends using polystyrene.
