Abstract
To provide a method for fractionating a liquid composition, which is excellent in separability of the liquid composition. This method for fractionating a liquid composition comprises discharging, from a discharge port of a filling nozzle, a liquid composition containing a solvent and a polymer having ion exchange groups, and fractionating a predetermined amount of the liquid composition, characterized in that the temperature of the liquid composition is controlled so that the average tan δ1 of the liquid composition when discharged from the discharge port of the filling nozzle becomes to be at most 1.00.

A method for fractionating a liquid composition, which comprises discharging a liquid composition containing a polymer having ion exchange groups and a solvent, from a discharge port of a filling nozzle, and fractionating a predetermined amount of the liquid composition,
- characterized in that the temperature of the liquid composition is controlled so that the average tan δ1 of the liquid composition when discharged from the discharge port becomes to be at most 1.00,
- wherein the average tan δ1 means an arithmetic mean value of the loss tangent tan δ (10 Hz) at a frequency of 10 Hz and the loss tangent tan δ (20 Hz) at a frequency of 20 Hz, which are obtained by dynamic viscoelasticity measurement conducted by changing the frequency from 1 Hz to 100 Hz under conditions of a strain of 1% and a temperature of T1 using the liquid composition, at the time when the temperature of the liquid composition discharged from the discharge port of the filling nozzle is set to be T1.
