摘要：
A mixture which contains a) 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 TgA is in the range from 40° to 90° C., b) 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 TgB is in the range from −70° to 0° C., c) a polystyrene C, and its use for the production of packaging for electronics components.
