Abstract

PURPOSE: To prepare the titled dispersing agent giving a coal-water slurry having high dispersion stability, excellent deashing characteristics, and high fluidity, by using a copolymer of (meth)acrylic acid and other vinyl monomers or a salt of the copolymer as an effective component.
CONSTITUTION: A dispersing agent containing one or more compounds selected from a copolymer of (meth)acrylic acid and other vinyl monomers (pref. styrene or 4W8C alkene), its salt (pref. alkali metal salt or ammonium salt), the hydrolyzate of a copolymmer of a (meth)acrylic acid ester and other vinyl monomers, and its salt, as effective components. The molar ratio of the acrylic monomer to the vinyl monomer is pref. 8/2W5/5, and the average molecular weight of the copolymer is pref. 2,000W20,000.
