Provided is a polymer flocculant which is capable of controlling the structure of a polymer that is a copolymerization product of a monomer (a) having a structure derived from formula (I) in each molecule and a water-soluble unsaturated monomer (b) having a polymerizable unsaturated bond in each molecule, and which has a branched or cross-linking structure, and is excellent in water-solubility and water dispersibility,
In formula (I), R1 and R2 are respectively a linear or branched functional group configured of atoms selected from the group consisting of carbon not having a carbon-carbon unsaturated bond, oxygen, nitrogen, and hydrogen; W is a non-metal element of the group 15; X and Y are each a linear or branched functional group configured of atoms selected from the group consisting of carbon, oxygen, nitrogen, and hydrogen, and each have at least one carbon-carbon unsaturated bond, provided that X and Y have different structures; and Z is a chlorine ion, a bromine ion, or an iodine ion.
