摘要：
The present invention relates to thermoplastic mixtures of 90 to 20% by weight of an aromatic polycarbonate with an Mw of 15,000 to 25,000 and p-(iso-C.sub.8 -C.sub.9 -alkyl)-phenyl end groups and 10 to 80% by weight of a polystyrene with an Mw of 80,000 to 400,000, and to their use as substrates for optical data memories.
