Polycarbonate compositions are disclosed. The compositions comprise a polycarbonate polymer (A) having repeating units derived from at least three different monomers, one monomer being 2-phenyl-3,3-bis(4-hydroxyphenyl)phthalimidine (PPPBP); and the other two monomers having the formula: wherein each Ris independently a halogen atom, a Chydrocarbon group, or a Chalogen substituted hydrocarbon group, and n is 0 to 4; and an impact modifier (B). The resulting composition has improved heat resistance and chemical resistance, particularly to Fuel C.
