摘要

Thermoplastic molding compositions comprising the following components:
a) 3 to 91.7 wt % of at least one aromatic polycarbonate, as component Ab) 3 to 91.7 wt % of one or more styrene copolymers, as component Bc) 3 to 91.7 wt % of one or more impact-modifying grafted rubbers without olefinic double bonding in the rubber plase, as component C, and alsod) 0.2 to 0.9 wt % of a compound of formula (I), as component D:;e) 0 to 0.9 wt % of a mixture of formula (II), as component E:;n=2 to 20f) 0 to 0.9 wt % of a triazine stabilizer, and also, optionally further components,
with the proviso that when component E amounts to 0 wt %, at least one further stabilizer is present in an amount of 0.01 to 0.9 wt %, have good weathering properties.
