COPOLYMER, DISPERSANT, AND DISPERSION COMPOSITION
Provided is a copolymer that can be used as a dispersant having high dispersibility and high slump retention capability.A copolymer according to an embodiment is a water-soluble copolymer that contains, as constituent monomers, at least one monomer selected from a monomer (A) represented by formula (1) and a monomer (B) represented by formula (2), and at least one monomer (C) selected from an unsaturated carboxylic acid monomer (C-1) and an oxyethylene group-containing unsaturated carboxylic acid ester (C-2). The content of the monomer (C) is 20 mass% or more and 99 mass% or less.D1:R1:
