Disclosed are polyestercarbonate copolymers comprising a carbonate unit of Formula (I), an ITR ester unit of Formula (V), and optionally a different carbonate unit of Formula (VI): wherein R, R, p, q, A, h, j, k, R, r, and Rare as described herein. The polyestercarbonate copolymers have a combination of scratch resistance, good flow, and good weatherability.

Polyestercarbonate copolymers with high scratch resistance

Polycarbonate compositions are disclosed. The compositions comprise an optional polycarbonate polymer (A); a polycarbonate-polysiloxane copolymer (B); a phosphorous-containing flame retardant (C); and a reinforcing agent (D). The resulting compositions have an improved combination of properties, particularly Vicat softening temperature and high flame retardance in thin walls.
