| titleOfInvention | Method and apparatus for producing polymer |
| abstract | [PROBLEMS] To polymerize a monomer component at a high concentration without the need to reduce the amount charged in a reactor, even in the case of a polymerization system in which a reaction solution easily foams during polymerization. The present invention provides a method and apparatus capable of producing a polymer having a low molecular weight and a narrow molecular weight distribution. SOLUTION: During a polymerization period, at least a part of vapor generated from a reaction liquid 10 is distilled off, and a liquid A having a temperature lower than a reaction temperature is added to the reaction liquid 10. The production apparatus includes a raw material supply pipe 2... And a reactor 1 to which a thermometer and the like are attached. Further, the reactor 1 is provided with an extraction pipe 6 for extracting vapor such as a solvent from the reactor 1 and an introduction pipe 5 for supplying the liquid A. At least a part of the vapor generated from the reaction solution 10 is discharged out of the polymerization system as a distillate via the extraction pipe 6 and the like, while the liquid A having a temperature lower than the reaction temperature is passed through the introduction pipe 5. To the reaction liquid 10. |
