摘要： The present invention provides a composition comprising polycarbonate wherein the polycarbonate has a very low Fries content (e.g., above 5 ppm and below 360 ppm). The present invention also provides a polycarbonate having a very low Fries content which is made by the melt process. This polycarbonate has high ductility and high impact strength. The invention also provides a method for making these compositions. Another aspect of the invention is an optical disk comprising polycarbonate having a very low Fries content which is made by the melt process. Such optical disks resist breakage due to bending.

摘要： 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.
