Transparent, tough and rigid molding compositions based on styrene-butadiene block copolymer mixtures

A block copolymer or graft copolymer with weight-average molar mass Mof at least 100 000 g/mol, comprising

Phase-separating block or graft copolymers comprising incompatible hard blocks and moulding compositions having a high stiffness

Highly transparent and tough-stiff styrene-butadiene block copolymer mixtures

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.

Transparent mixtures of linear styrene-butadiene block copolymers

A process for the preparation of linear polymers or block copolymers of styrene by anionic polymerization comprises carrying out the chain termination with an n-alkyl glycidyl ether or a dialkyl ketone.
