  • 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.

  • Patent number: 10703895
    Abstract: The present invention provides a water-soluble film having excellent solubility in cold water, high strength, and excellent hard-water resistance. The present invention also provides a method for simply producing such a water-soluble film. One aspect of the present invention relates to a water-soluble film including a polymer containing an anionic group other than a sulfonic acid (salt) group, and a water-soluble resin. The anionic group-containing polymer excludes an acrylic acid homopolymer. Another aspect of the present invention relates to a method for producing a water-soluble film that includes a polymer containing an anionic group other than a sulfonic acid (salt) group, and a water-soluble resin. The method includes mixing a polymer containing an anionic group other than a sulfonic acid (salt) group and a water-soluble resin.
