ABSTRACT:
The present invention relates to a process for the modification of thermoplastic aromatic polycarbonates containing aromatically bonded halogen, primary alkyl, secondary alkyl and/or alkenyl substituents, characterized in that these polycarbonates are irradiated with UV light, after adding between about 1 and 5% by weight, preferably between about 1 and 3% by weight, relative to the weight of polycarbonate, of photoinitiators and optionally between about 0.05 and 5% by weight, preferably between about 0.1 and 2% by weight, relative to the weight of polycarbonate, of flame-proofing agents. The present invention also relates to the modified polycarbonates obtainable by the process according to the invention.
