Improved color and hydrolysis stabilization of aromatic polycarbonate resins |
| abstract |
(57) An aromatic polycarbonate composition having improved color stability and improved hydrolysis stability while maintaining good processing characteristics. The composition of the present invention comprises an aromatic polycarbonate and a stabilizer system comprising at least one phosphorus-containing organic additive and hexamethylenetetramine. The stabilizer system is present in an amount sufficient to provide improved color stability as compared to using only the phosphorus-containing stabilizer. Preferred amounts of stabilizer are from about 0.01 to about 0.30% by weight, based on the combined weight of the polycarbonate resin and stabilizer. There is also provided a method of making an injection molded or extruded article having the improved properties described above, especially an article such as a transparent polycarbonate sheet. |
