A thermoplastic composition comprises a polycarbonate having repeating structural carbonate units of the formula (1): wherein at least 60 percent of the total number of R<SUP>1</SUP> groups contain aromatic organic groups and the balance thereof are aliphatic, alicyclic, or aromatic groups; and wherein the polycarbonate comprises terminal groups derived from reaction with a cyanophenol of the formula wherein Y is a halogen, C<SUB>1-3</SUB> alkyl group, C<SUB>1-3</SUB> alkoxy group, C<SUB>7-I2</SUB> arylalkyl, C<SUB>7-I 2</SUB> alkylaryl, or nitro group, y is 0 to 4, and c is 1 to 5, provided that y+c is 1 to 5; and a flame retardant. The composition may also comprise a branching agent. The compositions are useful in the manufacture of a wide variety of parts, particularly those having a thin wall.
