Abstract: The present disclosure relates to articles formed from polycarbonate prepared according to a melt polymerization method. The resulting articles exhibit mechanical properties improving upon articles formed from polycarbonate prepared according to conventional melt polymerization processes and are comparable to the mechanical properties apparent in articles prepared from interfacial polycarbonate compositions. Methods of preparing the melt polycarbonate composition are further disclosed herein.

Abstract: A molded article includes a polycarbonate resin, an ultraviolet (UV) absorbing component, a heat stabilizer component and an acid stabilizer component. The polycarbonate resin is produced by an interfacial polymerization process and has an end-cap level of at least about 98%, and includes a ratio of bound UV absorbing component to free UV absorbing component of less than about 1.0 when molded under abusive molding conditions. The polycarbonate resin may include high purity polycarbonate. The acid stabilizer component may include a sulfonic acid ester. Methods of forming molded articles are also described.
