Polycarbonate Resin Composition
29 Jan 20
Provided is a polycarbonate resin composition having the following features: even when the composition is retained in a molding machine at a high temperature exceeding 340° C., the composition shows little yellowing and hence maintains a satisfactory color tone; and even when a molded article obtained by molding the composition after the composition has been retained under a high-temperature condition undergoes thermal history, the molded article shows a small change in color tone with time and is hence excellent in long-term stability of its optical characteristics.
