DISPERSANT FOR HYDRAULIC COMPOSITION AND HYDRAULIC COMPOSITION CONTAINING THE SAME
PROBLEM TO BE SOLVED: To provide a dispersant for hydraulic composition high in coagulation rate, excellent in flow retention capacity and capable of suppressing increase of viscosity when made as a hydraulic composition and the hydraulic composition containing the same.SOLUTION: There is provided a dispersant for hydraulic composition containing a polycarboxylic acid copolymer containing a constitutional unit derived from a monomer represented by the formula (1), an unsaturated monocarboxylic acid-based constitutional unit and a constitutional unit derived from an unsaturated dicarboxylic acid monomer or a salt thereof (A). R-O-(AO)-R(1), where Ris C2 to 5, AO is each independently a C2 to 18 oxyalkylene group, n1 is average addition mole number of the oxyalkylene group and the number of 1 to 200 and Ris H or a C1 to 30 hydrocarbon group.SELECTED DRAWING: None
【課題】凝結速度が速く、流動保持性能に優れ、しかも水硬性組成物とした場合に、該水硬性組成物の粘性の増加を抑制することができる水硬性組成物用分散剤およびこれを含有する水硬性組成物を提供。【解決手段】式（１）で表される単量体に由来する構成単位と不飽和モノカルボン酸系の構成単位と不飽和ジカルボン酸系単量体に由来する構成単位とを含むポリカルボン酸系共重合体又はその塩（Ａ）を含む水硬性組成物用分散剤。Ｒ１−Ｏ−（Ａ１Ｏ）ｎ１−Ｒ２・・・（１）（Ｒ１はＣ２〜５；Ａ１Ｏは夫々独立にＣ２〜１８のオキシアルキレン基；ｎ１はオキシアルキレン基の平均付加モル数、１〜２００の数；Ｒ２はＨ又はＣ１〜３０の炭化水素基）【選択図】なし
