Abstract
The invention relates to polymer mixtures comprising A. an aromatic polycarbonate and B. a polyalkylene terephthalate. It has been found that the cosmetic properties of articles obtained by injection-moulding the polymer mixture can be improved by the addition of cross-linked polymer particles having an average particle size from 1 to 30 micrometers.
