Abstract: The invention relates to a process and device for the production of highly concentrated spinning solutions from acrylonitrile polymers, where the dissolving is carried out in one step in a stirred mixing vessel, which has a disc-shaped stirrer rotating in a horizontal plane, the polymeric material to be dissolved and the solvent are metered in separately at room temperature into the stirring vortex which is formed, and the temperature of the solution being formed is maintained at a constant preset value in the range from 60 DEG to 120 DEG C. by controlling the peripheral velocity of the stirrer.
