ABSTRACT:
A composition is disclosed having minimum halogen content, fire-retardance and/or drip-resistant characteristics. The composition comprises an effective amount of a polycarbonate, a glass fiber, a polysiloxane-polycarbonate copolymer, and a synergistic combination of an aromatic sulfone sulfonate such as potassium diphenylsulfone sulfonate with an aromatic sulfonate such as sodium salt of toluene sulfonic acid, optionally in the presence of an anti-drip agent. The polycarbonate composition is useful for manufacture of electronic and mechanical articles, among others.
