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.

Abstract: A molded article includes a polycarbonate resin and a colorant, and the molded article, when tested using a 3 mm color plaque, includes a color difference delta E (dE*) of less than about 0.6 following molding under abusive molding conditions as compared to a reference article molded under standard processing conditions. The molded article may include a color difference delta b (db*) of less than about 0.3 after being molded under the abusive molding conditions. The molded article may also exhibit a shift in wavelength of maximum absorbance of less than about 5 nm after being molded under the abusive molding conditions and/or a difference in absorbance intensity of less than about 15% after being molded under the abusive molding conditions as compared to a reference article molded under standard processing conditions. Methods for forming a molded article in accordance with the above are also described.

Abstract: A molded article includes a polycarbonate resin, an ultraviolet (UV) absorbing component, a heat stabilizer component, and a colorant. The molded article, when tested using a 2.5 mm color plaque, includes a color difference delta E* (dE*) of less than about 0.6 following molding under abusive molding conditions as compared to a reference article molded under standard processing conditions. The molded article may include a color difference delta b* (db*) of less than about 0.3 after being molded under the abusive molding conditions as compared to a reference article molded under standard processing conditions. The UV absorbing component may include a benzotriazole compound. Methods for forming a molded article in accordance with the above are also described.
