Abstract

Thermoplastic molding composition characterized in that the polymer proportion soluble in dichloromethane has a c50 value of acrylonitrile of ≧28 wt. % and a chemical distribution (c90−c10 value) of the acrylonitrile of ≧5 wt. % is disclosed. The composition is characterized by its improved processability by extrusion and thermoforming.
