Abstract
The present invention relates to a fluorescently-tagged (co)polymer and use thereof useful as a scale inhibitor in industrial water systems. Said (co)polymer comprises a (i) reactive fluorescent compound selected from a benzodiazole compound (ii) at least one monoethylenically unsaturated acid monomer, and (iii) optionally, at least one monoethylenically unsaturated acid-free monomer.
