Polycarbonate compositions

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); and an impact modifier (C) which is different f...

Summary: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); and an impact modifier (C) which is different from polymer (A) and polymer (B). The resulting composition has an improved combination of properties, particularly heat resistance, low temperature impact performance, and viscosity. Also disclosed are articles formed from such compositions.
