PROCESS FOR PRODUCING ACRYLONITRILE-BASED POLYMER SOLUTION, SHEARING DEVICE, PROCESS FOR PRODUCING ACRYLONITRILE-BASED FIBER, AND PROCESS FOR PRODUCING CARBON FIBER.
PROCESS FOR PRODUCING ACRYLONITRILE-BASED POLYMER SOLUTION, SHEARING DEVICE, PROCESS FOR PRODUCING ACRYLONITRILE-BASED FIBER, AND PROCESS FOR PRODUCING CARBON FIBER.
A process for producing an acrylonitrile-based polymer solution is provided with which it is possible to evenly and efficiently dissolve an acrylonitrile-based polymer in a solvent, inhibit the filter or spinning nozzle from clogging, and stably produce an acrylonitrile-based polymer solution. The process for producing an acrylonitrile-based polymer solution comprises supplying a mixture of the polymer and a solvent to the dispersion chamber of a shearing device comprising a cylinder and a rotor that rotates inside the cylinder, rotating the rotor under the following conditions to apply shear force to the mixture, and thereafter heating the obtained mixture to obtain an acrylonitrile-based polymer solution. W=(W1-W2)/M≥0.12 (kWh/kg). W1, W2, and M are defined in the description. Alternatively, the conditions may be changed so that W≥1.60, and the heating may be omitted.
