POLYCONDENSATION PRODUCT, AND DISPERSANT FOR HYDRAULIC COMPOSITION CONTAINING THE SAME
PROBLEM TO BE SOLVED: To provide a polycondensation product containing a novel phenolic copolymer useful for a dispersant for hydraulic compositions.SOLUTION: The present invention provides a polycondensation product containing a copolymer obtained by polycondensation of a monomer mixture containing a compound A represented by formula (A), and an aromatic compound having a phosphate group or sulfate group and an aldehyde compound, and a dispersant for hydraulic compositions containing the same (Ris H, an alkyl group, an alkoxy group or an alkenyl group; AO is an alkyleneoxy group; m is the number of 1 to 300; Ris H, an alkyl group or an acyl group).SELECTED DRAWING: None
【課題】水硬性組成物用分散剤に有用な新規なフェノール系共重合体を含有する重縮合生成物の提供。【解決手段】式（Ａ）で表される化合物Ａと、リン酸エステル基又は硫酸エステル基を有する芳香族化合物及びアルデヒド化合物と、を含む単量体混合物を重縮合させた共重合体を含む重縮合生成物、及びそれを含有する水硬性組成物用分散剤。（Ｒ１はＨ、アルキル基、アルコキシ基又はアルケニル基；Ａ１Ｏはアルキレンオキシ基；ｍは１〜３００の数；Ｒ２はＨ、アルキル基又はアシル基）【選択図】なし
