Halogen-containing polycarbonate resin and process for producing same |
| abstract |
A halogen-containing polycarbonate resin is formed by copolymerizing the following oligomers (a) and (b) in the presence of caustic alkali an organic solvent and water and in the substantial absence of bisphenol A: (a) 10 to 85 parts by weight of a polycarbonate oligomer with terminal groups consisting of chloroformate groups or chloroformate groups plus hydroxyl groups in a molar amount less than the chloroformate groups, having a number average molecular weight of 500 to 10,000 and containing no aromatic halogen or less than 4% by weight of aromatic halogen, and (b) 90 to 15 parts by weight of an aromatic halogen-containing polycarbonate oligomer with terminal groups consisting of chloroformate groups or chloroformate groups plus hydroxyl groups in a molar amount less than the chloroformate groups, having a number average molecular weight of 1,000 to 10,000 and containing 6 to 30% by weight of aromatic halogen. |
