    Abstract: PROBLEM TO BE SOLVED: To provide a preparation process of an aqueous secondary dispersion liquid for a water insoluble polymer without using a surfactant.
    SOLUTION: The preparation process of an aqueous secondary dispersion liquid for a water insoluble polymer is characterized by performing a free radical solution polymerization in a polymerization medium, either an organic/water miscible solvent or a mixture of water and an organic/water miscible solvent, of an ethylenic unsaturated monomer M containing (i) at least one kind of monoethylenic unsaturated monomer M1 with the water solubility of 30 g/l or less at 25°C and 1 bar and (ii) at least one kind of hydrophilic and monoethylenic unsaturated nonionic comonomer M2 with the water solubility of 80 g/l or less at 25°C and 1 bar, replacing the solvent with water, and adding some amount of the monomer M as a monomer composition M' consisting essentially of the monomer M2 before completing the polymerization. The water-soluble polymer dispersion liquid is also provided and the use of the above liquid especially in pharmacology and cosmetics is specified.
