Abstract
PURPOSE:To obtain the titled additive capable of realizing 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 ampholytic surfactant 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) an ampholytic surfactant [e.g. (sulfo)betaine, glycine, alanine or imidazoline type] together. Furthermore, the weight ratio of the components (A) to (B) used is preferably within the range of 99/1-50/50.
