Abstract

[PROBLEMS] To prevent the deposition of a silica-containing stain which is formed in a cooling water system, a boiler water system, a membrane treatment apparatus or the like. [MEANS FOR SOLVING PROBLEMS] Disclosed is an agent for preventing the deposition of a silica-containing stain, which comprises a polymer produced by the copolymerization of a monomer having a carboxyl group, an isoprene sulfonic acid monomer represented by the formula (1) and a monomer having an unsubstituted or substituted acrylamide represented by the formula (2). The agent can prevent the deposition of a silica-containing stain efficiently. (1) (2)
