Abstract: A polycarbonate copolymer contains aromatic carbonate units; optionally siloxane units; and resorcinol arylate ester units. The resorcinol arylate ester units of the polycarbonate copolymer are derived from a resorcinol composition having a hydroquinone content of 50 to 1200 parts per million, a catechol content of 5 to 29 parts per million, and a phenol content of 0 to 2400, each as determined by high performance liquid chromatography, and further comprising an acid stabilizer.
