Beschreibung
Zusammenfassung:	The invention relates to the use of PMMI copolymers for reducing the molecular weight degradation of the polymer induced by oxides such as titanium dioxide or silicon dioxide in compositions based on aromatic polycarbonate. The mechanical, optical and rheological properties of the thermoplastic composition remain good and are in some cases even improved despite the addition of the PMMI copolymer.
