ABSTRACT:
A monomer having a structure expressed as: ##STR1## wherein R.sub.1 is a hydrogen atom, --OH group, --COOR.sub.5 group, or group expressed as: ##STR2## R.sub.2 is a hydrogen atom, --CH.sub.3 group, or --CH.sub.2 COOR.sub.4 group, R.sub.3 is a hydrogen atom, --OH group, or --CH.sub.2 COOR.sub.4 group, R.sub.4 is a hydrogen atom, sodium atom, potassium atom, or --NH.sub.4 group, and R.sub.5 is a sodium atom, potassium atom, or --NH.sub.4 group; a polymer having a structure unit expresses as: ##STR3## wherein R.sub.1 through R.sub.5 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.
