Abstract

The invention is directed towards methods and compositions for making and using fluorescent monomers which are synthesized by reacting a substituted or non-substituted benzoxanthene anhydride with an amine and with a moiety containing a polymerizable group. Such monomers are useful for the preparation of tagged treatment polymers. Such tagged treatment polymers are useful as scale inhibitors in industrial water systems.

First claim

What is claimed is:

1. A method of monitoring an industrial water system, comprising:
(a) adding an inert tracer and a tagged treatment polymer to water resulting in a tagged treatment polymer concentration;
(b) detecting fluorescent signals from the inert tracer and the tagged treatment polymer;
(c) adjusting the amount of tagged treatment polymer concentration in the water;
