摘要： A polar solvent solution of the present invention is a polar solvent solution in which a solute containing a polyamino acid is dissolved in a polar solvent. An inorganic salt is added to the solution, and a mole ratio of moisture to the inorganic salt in the solution is 2.5 × m × n or less, where m represents the number of cations forming the inorganic salt and n represents a charge number of the cation. A production method of the present invention is a method for producing the above solution, including: changing at least one of a moisture content and a content of the inorganic salt in the solution to adjust a viscosity of the solution. Thus, the present invention provides a polar solvent solution whose viscosity can be easily adjusted to a desired value and thus enables stable spinning and casting when used as dopes for spinning, film, etc., and methods for producing the same.

摘要： A polar solvent solution of the present invention is a polar solvent solution in which a solute containing a polyamino acid is dissolved in a polar solvent. The solution has a moisture content of less than 5 mass% based on 100 mass% of the solution. A method for producing a polar solvent solution of the present invention includes changing a moisture content of the solution to adjust the viscosity of the solution. Further, another method for producing a polar solvent solution includes reducing a moisture content of the solution to increase the viscosity of the solution. Thus, the present invention provides a polar solvent solution that enables stable spinning and casting without lowering its viscosity when used as dopes for spinning, film, etc., and methods for producing the same.
