ABSTRACT:
A polycarbonate composition is disclosed having zero or minimum halogen content, while also exhibiting improved fire-retardance and/or drip-resistant characteristics. The composition comprises an effective amount of a polycarbonate, an anti-dripping agent, an aromatic sulfone sulfonate, an aromatic sulfonate, a synergistic combination of an elastomer-modified graft copolymer and a polysiloxane-polycarbonate copolymer, and an optional siloxane oligomer. The polycarbonate composition is useful for manufacture of electronic and mechanical articles, among others.
