摘要: An isosorbide-containing polycarbonate composition is provided. The composition contains a polycarbonate having repeat units derived from isosorbide, a polycarbonate-property-modifying additive, and a pH stabilizer. When a solution containing 10 wt. % of the composition dissolved in dichloromethane is prepared the solution has a non-aqueous pH in a range of equal to or between 0.8 below and 0.5 above the pH of the dichloromethane.
