Polycarbonate compositions having enhanced optical properties, methods of making and articles comprising the polycarbonate compositions

A method of making a polycarbonate composition comprising:

• polymerizing by an interfacial polymerization, reactants comprising a starting material comprising a bisphenol-A to form a bisphenol-A polycarbonate, wherein the bisphenol-A has a purity of greater than or equal to 99.65 wt % and a sulfur content of less than or equal to 2 ppm;
• wherein the polycarbonate composition has a free hydroxyl content of less than or equal to 150 ppm, and wherein a molded article of the polycarbonate composition has transmission level greater than or equal to 90.0% at 2.5 mm thickness as measured by ASTM D1003-00 and a yellow index (YI) less than or equal to 1.5 as measured by ASTM D1925, and wherein the molded article comprises an increase in yellow index (YI) of less than 2 during 2,000 hours of heat aging at 130° C.
