| abstract |
The invention relates to a thermoplastic molding composition made from polystyrene (component A) and a non-elastomeric, star-branched block copolymer (component B), which is composed of 60 to 95% by weight of a monovinyl aromatic monomer and 40 to 5% by weight of a conjugated diene , and a lubricant (component C) in a proportion of 0.1 to 5 wt .-%, based on A + B + C. A polystyrene with a viscosity number in the range from 65 to 78 ccm / g is used as component A, which has a molecular non-uniformity Mw / Mn of greater than 1.5; component A is present in a proportion of 2 to 45% by weight, based on A + B + C. The molding compound is used for the production of molded parts, in particular packaging materials. |
