<P>PROBLEM TO BE SOLVED: To provide a production method in which a liquid rheology modifier can be obtained, wherein the liquid rheology modifier has moderate viscosity, is excellent in stability, uniformly shows its rheology modifying effect at short times without depending on temperature, and can improve the strength of a cured body at low temperature with regard to a hydraulic slurry. <P>SOLUTION: The liquid rheology modifier is produced that comprises, in an amount within a specific range, a compound (A) expressed by general formula (1), a dicarboxylic acid (B), a monocarboxylic acid (C), a cationic polymer (D), and propylene glycol (E). The compound (A) can be obtained by using amine and an anionic aromatic compound as raw materials, wherein the molar ratio of the anionic aromatic compound to the amine is 0.93 to 1.02. <P>COPYRIGHT: (C)2012,JPO&INPIT |
