  • Publication number: 20210009739
    Abstract: The present invention provides a (meth)acrylic acid copolymer-containing composition which can sufficiently exhibit both stability at low temperatures and a calcium phosphate scale inhibition ability. The present invention relates to a (meth)acrylic acid copolymer-containing composition containing a (meth)acrylic acid copolymer including: a structural unit (a) derived from at least one selected from the group consisting of (meth)acrylic acid and salts thereof; and a structural unit (b) derived from a sulfonic acid monomer (B), the copolymer containing the structural unit (b) in a proportion of 5 to 90 mol % based on 100 mol % of all structural units, and having a weight average molecular weight of 4,500 to 18,000, the composition containing a sulfur-containing inorganic component not incorporated into the copolymer at a concentration of 6,000 ppm or lower in terms of sulfur atoms.

  • Publication number: 20200392270
    Abstract: A sulfonate group-containing copolymer is provided which comprising a structural unit (a) derived from a sulfonate group-containing monomer (A); a structural unit (b) derived from a (poly)oxyalkylene monomer (B); a structural unit (c) derived from a carboxyl group-containing monomer (C). The sulfonate group-containing copolymer comprises from 20% to 90% by mass in an acid form equivalent of the structural unit (c) in 100% by mass of all the structural units constituting the sulfonate group-containing copolymer. The product (P×Mw×n) of the ratio by mass P of the structural unit (b) to the structural unit (a) multiplied by the weight average molecular weight Mw of the sulfonate group-containing copolymer multiplied by the value n is from 950,000 to 800,000,000.
