ABSTRACT:
An aromatic polycarbonate resin composition having hydroxyl groups as end groups is thermally stable and also offers excellent resistance to hydrolysis. The polycarbonate resin composition incorporates (A) an aromatic polycarbonate resin containing hydroxyl groups in the proportion of 5% or more of the total end groups and a metal impurity and (B) a deactivating agent selected from the group consisting of phosphorous acid, a thioether compound, a phosphite diester and a nitrogen-containing organic compound. The amount of deactivating agent is based on the amount of metal impurity in (A) and the type of deactivating agent.
