Abstract

The thermoplastic molding compositions proposed compriseA) from 20 to 90% by weight, preferably from 30 to 80% by weight, particularly preferably from 40 to 75% by weight, of a thermoplastic polymer, andB) from 10 to 80% by weight, preferably from 20 to 70% by weight, particularly preferably from 25 to 60% by weight, of a crosslinked rubber having two or more phases,where the polymer A has a viscosity number, measured on a 0.5% strength solution in dimethylformamide at 23° C., of from 50 to 70 ml/g, preferably from 55 to 65 ml/g, and where at least 80% by number, preferably at least 85% by number, particularly preferably at least 90% by number, of the rubber particles B in the dispersion, after the preparation thereof, have a diameter of <0.2 &mgr;m, preferably <0.18 &mgr;m, particularly preferably <0.15 &mgr;m.
