摘要：PROBLEM TO BE SOLVED: To provide a water-soluble polymer which, is possible to suppress the decrease in each scale inhibitory power due to using another water treating agent together with the polymer, and further has excellent water-solubility and water dispersibility. SOLUTION: The water-soluble polymer is characterized in comprises a constituent unit (A) derived from a monomer (a) having an epoxy group and a monoethylenically unsaturated double bond, another constituent unit (B) derived from another monomer (b) having another ethylenically unsaturated double bond different from that of the monomer (a), and still another constituent unit (C) derived from an amine compound (c) having an amino group.
