    摘要： Provided is a novel copolymer that can express an excellent calcium ion-trapping ability. The copolymer of the present invention includes: 0.1 mol% to 99 mol% of a structural unit (A) derived from a monoethylenically unsaturated monocarboxylic acid (salt) monomer (a); 0.1 mol% to 99 mol% of a structural unit (B) derived from a monomer (b) serving as a monoethylenically unsaturated dicarboxylic acid (salt) or an anhydride thereof; and 0.1 mol% to 50 mol% of a structural unit (C) derived from an ether bond-containing hydrophobic monomer (c).
