Abstract: The present invention relates to a polymer composition comprising—polycarbonate; -(meth)acrylic polymer; and-≥1.0 and ≤10.0 wt % polyalkylene glycol with regard to the total weight of the polymer composition. Such polymer composition can be produced by for example a conventional compounding process using melt extrusion, wherein polycarbonates and PMMA can be converted into a polymer composition having the desired properties without need for using dedicated process equipment.
