Document Type and Number:
WIPO Patent Application WO/2017/030002
Kind Code:
A1
Abstract:
A water-soluble polymer composition that includes a water-soluble polymer that includes 40-95 parts by mass of a structural unit (A) derived from a carboxyl-group-containing unsaturated monomer, 5-30 parts by mass of a structural unit (B) derived from a (meth)acrylamide derivative that has a C1-8 alkyl group, and 0-35 parts by mass of a structural unit (C) derived from another monomer (provided that (A)-(C) total 100 parts by mass) and that is provided with a structural unit (D) derived from one or more compound selected from among phosphorous acid compounds and hypophosphorous acid compounds. The water-soluble polymer composition has a free phosphorus compound content of 2.0 mass% or less.
