摘要:
The invention relates to a process for the production of vinyl copolymers with grafted-on polycarbonate chains, to the grafted vinyl copolymers obtainable by the process according to the invention, to their use as modifiers for mixtures of thermoplastic polycarbonates and thermoplastic polystyrenes, to such mixtures themselves and to the use of such mixtures as substrates for optical discs.
