摘要： A composition is provided that contains an intermediate for a water-soluble monomer, wherein this intermediate is suitable for producing a water-soluble polyalkylene glycol-type monomer that has a polymerizable terminal double bond, and suitable for the production of water-soluble polymer, and moreover allows the high-yield production of water-soluble polymer. A process of producing this composition and a water-soluble monomer-containing composition obtained therefrom are also provided. A water-soluble monomer is also provided that can be used as a starting material for a water-soluble polymer that even at high harnesses exhibits an excellent capacity to capture metal ions such as the calcium ion and magnesium ion, an excellent anti-gelation performance, an excellent anti-soil redeposition performance, a better anti-dye transfer performance than in the past, and also an excellent compatibility with surfactants. A production process is also provided that can produce such a water-soluble monomer at higher yields and higher selectivities (higher purities) than in the past. A composition containing an intermediate for a water-soluble monomer, that contains a compound (A) having a specified structure and that contains a specified amount of a compound (B) having a specified structure. Also, a water-soluble monomer having a specified structure is provided.

摘要： 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).
