Beschreibung
Zusammenfassung:	A method for producing an acrylonitrile polymer solution is provided, which can uniformly and effectively dissolve an acrylonitrile polymer in the solvent, and suppress the clog of a filter and a spinning nozzle, and stably produce the acrylonitrile polymer solution. In the method for producing the acrylonitrile polymer solution, the mixture of the polymer and a solvent are supplied to a dispersion chamber of a shear apparatus containing a cylinder and a rotor rotating inside of the cylinder, and the rotor is rotated under the conditions described hereinafter so as to apply a shearing force to the mixture, and subsequently, the mixture is heated to obtain the acrylonitrile polymer solution: W = (W1-W2)/M ≥ 0.12 (kWh/kg), wherein W1, W2, and M are defined in the specification. In addition, when W ≥ 1.60, the heating process is not required.
