由度を増すことができる。The water-soluble polymer-containing liquid composition of the present invention is considered to have a complicated heterogeneous system of the oil phase, the salt aqueous solution phase and the polymer fine particles. For this reason, the dispersion in oil (A) forms fine droplets, the phase inversion becomes easy, and the solubility is improved. Since the oil is no longer in the continuous phase, sedimentation and separation of polymer fine particles does not occur and flammability is also suppressed. The dispersion (B) in the aqueous salt solution has long-term storage stability increased by the action of preventing direct contact with the surface of the polymer fine particles. In the water-soluble polymer-containing liquid composition of the present invention, the polymer fine particles in the oil dispersion (A) and the polymer fine particles in the salt aqueous solution dispersion (B) are independently and directly contacted with each other. Due to their presence, both can be mixed in any proportions, increasing the freedom with respect to polymer composition and concentration.
