ABSTRACT:
A carbonate polymer composition comprising a carbonate polymer such as a bisphenol-A homopolycarbonate which carbonate polymer contains an amount of a salt represented by the formula: ##STR1## wherein Ar is an aromatic group, R is a monovalent organic moiety, or Ar and R collectively are a divalent aromatic moiety M is a cation, and n is a number corresponding to the valence of M and an amount of a free aromatic sulfimide, which carbonate polymer composition resists combustion upon exposure to an ignition source, exhibits good optical properties, and exhibits molecular weight stability. Optionally, a halogenated organic compound may be added to the composition.
