Title:
水溶性高分子分散液及びその製造方法
Document Type and Number:
Japanese Patent JP5187927
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To develop a water-soluble polymer dispersion containing a dispersing agent enabling the efficient production of the water-soluble polymer without thickening the polymerization dispersion, in a dispersion polymerization method in the coexistence of a polymer-dispersing agent in a salt aqueous solution, and to provide a method for producing the water-soluble polymer dispersion, by which the water-soluble polymer dispersion can efficiently be produced. SOLUTION: The water-soluble polymer dispersion can be obtained by the coexistence of at least one of polyoxyethylene chain-having graft copolymers soluble in the salt aqueous solution as a dispersing agent on the polymerization. Further, the water-soluble polymer dispersion can efficiently be produced by the coexistence of the graft copolymer on the polymerization.
