Abstract
The present invention provides a carboxyl group-containing polymer and a composition containing the polymer which exhibit excellent anti-soil redeposition ability in fabric washing. The carboxyl group-containing polymer includes specific ratios of a structure unit (a) derived from an ether bond-containing monomer (A), a structure unit (b) derived from a sulfonic acid group-containing monomer (B), and a structure unit (c) derived from an acrylic acid-based monomer (C), and has a specific weight average molecular weight. The carboxyl group-containing polymer composition contains the carboxyl group-containing polymer and a specific amount of a hydrogen sulfite adduct of the acrylic acid-based monomer (C).
