Abstract
The invention relates to thermoplastic aromatic polycarbonates which structural units are characterized by their end groups which are residues of ##STR1## and is predicated on the surprising and unexpected findings that high melt flow polycarbonates of this type are rendered improved impact performance by admixing therewith small amounts of an impact modifier.
