| titleOfInvention | Method for producing halogen-containing polycarbonate resin |
| abstract | PROBLEM TO BE SOLVED: To provide a method for efficiently producing a halogen-containing polycarbonate resin excellent in detergency and granulation property without lowering the molecular weight. The number average molecular weight is 500 to 5000, halogen-free or halogen content is less than 4% by weight (excluding chlorine of the terminal chloroformate group), and chloro with respect to the phenolic hydroxyl group at the end of the oligomer. A carbonate oligomer characterized in that the ratio of formate groups is 1: 3 to 1:20. The number average molecular weight is 1000 to 10,000, the halogen content is 6 to 30% by weight (excluding chlorine of the terminal chloroformate group), and the ratio of chloroformate group to phenolic hydroxyl group at the terminal of the oligomer is 1: A halogen-containing carbonate oligomer characterized by having a ratio of 5 to 1:50. And the manufacturing method of the polycarbonate which copolymerizes said 2 types of oligomer. [Selection figure] None |
