Zusammenfassung:The present invention is a carbonate polymer composition comprising a carbonate polymer having dispersed therein a metal salt of an aromatic sulfimide and a metal sulfate or bisulfate having a pka from 1 to 5 inclusive whereby the sulfimide is used in an amount to provide improved flame retardancy and sulfate or bisulfate is used in an amount to provide increased processing stability. The use of metal sulfates or metal bisulfates is effective in reducing molecular weight changes during melt shearing.
