COPOLYMER, DISPERSANT, AND DISPERSION COMPOSITION
Provided is a copolymer which is able to be used as a dispersant that has excellent dispersibility and excellent slump retention ability. A copolymer according to one embodiment of the present invention is a water-soluble copolymer which contains, as constituent monomers, at least one monomer selected from among monomers (A) represented by formula (1) and monomers (B) represented by formula (2) and at least one monomer (C) selected from among unsaturated carboxylic acid monomers (C-1) and oxyethylene group-containing unsaturated carboxylic acid esters (C-2), and which is configured such that the content of the monomer (C) is from 20% by mass to 99% by mass (inclusive).
本发明提供一种可作为分散性与坍落度保持性优异的分散剂使用的共聚物。实施方式涉及的共聚物为一种水溶性共聚物，其中，作为构成单体而包含：选自式(1)所表示的单体(A)及式(2)所表示的单体(B)中的至少一种单体；以及选自不饱和羧酸系单体(C‑1)及含有氧亚乙基的不饱和羧酸酯(C‑2)中的至少一种单体(C)，并且单体(C)的含量为20质量％以上且99质量％以下。
