Polycarbonate compositions are disclosed. The compositions comprise a polycarbonate polymer (A) having repeating units derived from 2-phenyl-3,3-bis(4-hydroxyphenyl)phthalimidine (PPPBP); a polycarbonate polymer (B) which is different from polymer (A); an impact modifier (C) which is different from polymer (A) and polymer (B); and talc filler (D). The resulting composition has an improved combination of properties, particularly heat resistance, low temperature impact performance, and viscosity.
