A polymer having the function of water treatment and labeled with a fluorescent substance having a allyl group is disclosed. A process for producing the polymer for water treatment having the function of water treatment and labeled with a fluorescent substance having allyl group comprises copolymerizing a fluorescent substance having allyl group obtained by introducing allyl group into a fluorescent substance using a Grignard reagent with a monomer having a polymerizable double bond. The polymer having the function of water treatment and labeled with a fluorescent substance having an allyl group can be obtained under atmospheric pressure. Concentration of the polymer for water treatment can be measured conveniently, accurately and quickly. Therefore, concentration of the polymer in water can be easily adjusted to the optimum value. Degradation of the labeled polymer by chlorine can be prevented when an agent for water treatment containing the labeled polymer and a hydantoin compound is used.
An improved agent for water treatment which comprises a polymer having the function of water treatment for corrosion prevention or scale prevention wherein the improvement comprises said polymer incorporating units of a labeled monomer which is labeled with a fluorescent substance and has an allyl group.
