Abstract

See full text

Flame retardant carbonate polymer compositions and articles prepared therefrom are described. The carbonate polymer contains a flame retardant additive comprising metal salts of a highly fluorinated methide, amide or imide anion. The composition provides flame retardancy at relatively low levels of additive, allows a broader processing window of additive compositions and can have high transparency.
