Abstract

The invention relates to compositions containing polycarbonate and carboxylic acid esters of isosorbide, to the use of the compositions for the production of blends or shaped parts and to molded parts obtained therefrom. The compositions have improved rheological and optical properties and an improved demolding and processing behavior in the injection-molding process.
