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.
一种模塑制品包括聚碳酸酯树脂、紫外线(UV)吸收成分、热稳定剂成分和酸稳定剂成分。聚碳酸酯树脂是通过界面聚合工艺生产的,端盖含量至少约为 98%,在恶劣的成型条件下成型时,结合紫外线吸收组分与游离紫外线吸收组分的比率小于约 1.0。聚碳酸酯树脂可包括高纯度聚碳酸酯。酸稳定剂成分可包括磺酸酯。此外,还介绍了模塑制品的成型方法。
