Abstract
PURPOSE:To obtain the titled additive capable of realizing a high concentration of a slurry and providing shearing resistance and standing stability for a long period, by using a sulfonic acid group-containing aromatic hydrocarbon based polymer (salt) and specific polyamine, etc., together. CONSTITUTION:The aimed additive obtained by using (A) (i) a polymer prepared by polymerizing a polymerizable aromatic sulfonic acid based monomer group as an essential component and, as necessary, adding and polymerizing other polymerizable hydrocarbon based monomer groups and/or (ii) a sulfonated polymer obtained by polymerizing a polymerizable hydrocarbon based monomer group containing a polymerizable aromatic monomer as an essential component and sulfonating the resultant polymer and (B) (i) a polyamine or polyamide expressed by formula I (R1 is 1-30C alkyl, etc.; R2 is H, 1-30C alkyl, etc.; lis 0 or 1; m is 1-4) or (ii) a polyamide prepared by reacting a 2-30N polyamine having the main skeleton expressed by formula II or III with a 6-30C fatty acid or an alkylene oxide adduct (derivative thereof) of the component (i) or (ii) together.
