摘要: The present invention provides a method for making a polycarbonate composition. The polycarbonate is prepared by melt synthesis using a sulfur-containing acid compound to at least partially quench the melt catalyst. The polycarbonate composition comprises said polycarbonate, phosphorous acid, further sulfur-containing acid compound and an ester derived from a mono-fatty acid and a polyhydric alcohol.
