POLYCARBOXYLATE-BASED COPOLYMER AND DISPERSING AGENT THEREWITH
PROBLEM TO BE SOLVED: To provide a new polycarboxylate-based copolymer which has stable dispersibility without depending on content of impurity in aggregate, can be provided appointed flowage without changing addition quantity substantially for the type of the aggregate and is useful for a dispersing agent for hydraulic composition.SOLUTION: A polycarboxylate-based copolymer is provided by copolymerizing monomeric mixture containing alkylene oxide adduct of alkadienol and unsaturated carboxylic monomer. A dispersing agent for hydraulic composition contains the copolymer.SELECTED DRAWING: None
【課題】骨材中の不純物の含有量によらず安定した分散性を有し、骨材の種類によって添加量を実質変えなくとも所定の流動性が得られる水硬性組成物用分散剤に有用な新規なポリカルボン酸系共重合体を提供すること。【解決手段】アルカジエノールのアルキレンオキサイド付加物及び不飽和カルボン酸系単量体を含む単量体混合物を共重合させて得られる、ポリカルボン酸系共重合体及び該共重合体を含有する水硬性組成物用分散剤。【選択図】なし
