1. A process for manufacturing a polycarbonate composition comprising:
melt polymerizing a dihydroxy compound and a carbonate compound in the presence of a catalyst to form a polycarbonate; and adding 1 to 400 ppm of glycerol tristearate to form the polycarbonate composition, wherein the polycarbonate composition is unquenched, wherein the polycarbonate has a weight average molecular weight of 8,000 to 19,000 Daltons as determined by gel permeation chromatography and based on polycarbonate standards. |
