Abstract
【課題】 炭酸カルシウムの分散安定化効果が高く、ハンドリング性に優れ、特に重質炭酸カルシウムの湿式粉砕処理用の分散剤として好適な炭酸カルシウム用分散剤の提供。 【解決手段】 (メタ)アクリル酸系共重合体(A)［(メタ)アクリル酸(塩)由来の構造単位(a)と式；CH２＝C(R１)－COO－(CH２)ｍ－(R２－O)ｎ－R３（式中R１はH又はMt、R２はプロピレン基、R３はH又は１価の炭素数1～6の炭化水素基、mは0～4、ｎは2～10)で表される(メタ)アクリル酸エステル由来の構造単位(b)を有する、Xa／Xb＝3～15［Xa＝構造単位(a)のモル％、Xb＝{構造単位(b)のモル％}×{構造単位(b)でのプロピレンオキサイド単位の付加モル数ｎ｝］を満足し、Mn＝2000～4000の(メタ)アクリル酸系共重合体］からなる炭酸カルシウム用分散剤、あるいは、(メタ)アクリル酸系共重合体(A)と（メタ）アクリル酸系重合体(B)とを8:2～2:8で混合した炭酸カルシウム用分散剤。
