Abstract
A composition includes a polycarbonate resin formed via an interfacial polymerization process and from 0.05 ppm to 50 ppm of a sulfonic acid. A molded article formed from the composition may exhibit a yellowness index that is less than that of a reference molded article formed from substantially similar polycarbonate composition comprising the polycarbonate resin but in the absence of the sulfonic acid. Methods for forming the molded article in accordance with the above are also described.
