Abstract
Particularly high-grade blends of thermoplastic polycarbonates, graft copolymers and, optionally, further thermoplastic resins, useful as moulding materials with good low-temperature impact strength and resistance to ageing and light, which yield mouldings with superior surfaces, are obtained from graft bases which are silicone rubbers containing sulphur in addition to groups containing carbon double bonds.
