  • Publication number: 20210284820
    Abstract: An aqueous solution and an aqueous dispersion of a composition that contains a polyalkylene oxide, a phenolic antioxidant and a sulfur-containing amine compound are less likely to impair the stability of the polyalkylene oxide even in the case of containing an alkali. In the above composition, the content of each of the phenolic antioxidant and the sulfur-containing amine compound is preferably set to 0.001 to 5 pasts by mass based on 100 parts by mass of the polyalkylene oxide, and the ratio of the sulfur-containing amine compound relative to 100 parts by mass of the phenolic antioxidant is preferably set to 20 to 200 pasts by mass.

  • Patent number: 10398917
    Abstract: The invention provides a drag reducer having an excellent frictional drag-reducing effect on an aqueous medium and the like and also provides a fire-extinguishing agent including this drag reducer. The drag reducer according to the present invention includes a polyalkylene oxide aqueous dispersion that includes a polyalkylene oxide, aluminum oxide, an electrolyte, and water, and that has the polyalkylene oxide dispersed therein. The drag reducer has an excellent frictional drag-reducing effect on an aqueous medium and the like.
