Abstract: A method for manufacturing a polycarbonate composition having improved transparency can comprise reacting an aromatic dihydroxy compound and a diaryl carbonate under melt polymerization conditions to provide a polycarbonate; and contacting the polycarbonate with a polydiorgano siloxane having a kinematic viscosity of less than 20 mm2/sec at 25° C. as determined in accordance with ASTM D445, and an optional additive thereby making the polycarbonate composition. The polycarbonate composition has haze less than 1% as determined in accordance with ASTM D1003-07, and can be used for optical applications such as automotive headlamps.
