A monomer having a structure expressed as: wherein R1 is a hydrogen atom, -OH group, -COOR5 group, or group expressed as: R2 is a hydrogen atom, -CH3 group, or -CH2COOR4 group, R3 is a hydrogen atom, -OH group, or -CH2COOR4 group, R4 is a hydrogen atom, sodium atom, potassium atom, or -NH4 group, and R5 is a sodium atom, potassium atom, or -NH4 group; a polymer having a structure unit expresses as: wherein R1 through R5 are identical with the above; and a composition containing a polymer that excels the conventional chleating agents in chleating and dispersing effects besides rendering excellent biodegradability. Therefore, the composition is preferably used as a detergent composition, an inorganic pigment dispersing agent, a fiber treatment agent, a water treatment agent (anti-scale agent), and a bleaching assistant for wood pulp, etc.
