Abstract:
A method for producing a spinning solution for producing a polymer fiber, particularly a p-aramid fiber, the polymer being blended with a solvent, mixed, melted, homogenized, and degassed and then discharged, liquid sulfuric acid being used as the solvent and at least the mixing, homogenization, and degassing taking place in a preferably continuously operated single or double cell reactor (1).
