ABSTRACT:
A process for producing a fire resistant polycarbonate composition comprises preparing an aqueous solution of a flame retardant salt; and compounding the aqueous solution of the flame retardant salt with a polycarbonate composition to form the fire resistant polycarbonate composition. The process reduces the level of haze, color and inclusions compared to fire resistant polycarbonate compositions compounded with the same flame retardant salt in solid form.
