摘要： PROBLEM TO BE SOLVED: To provide a dispersant for gypsum which, even when used in a small amount, is capable of providing even a gypsum slurry in which less water is used and which consequently has a lower water/gypsum ratio with sufficient flowability. SOLUTION: As the dispersant, a water-soluble vinyl copolymer is used which has a weight average molecular weight of 5,000-100,000 and is obtained by subjecting one specific vinyl monomer having a long polyoxyethylene group per molecule and two other specific vinyl monomers to a copolymerization reaction in their respective prescribed ratios.
