Abstract

The present invention relates to methods and compositions for making and using fluorescent monomers by reacting substituted or unsubstituted benzoxanthenic anhydrides with amines and with moieties containing polymerizable groups synthesis. Such monomers are useful for the preparation of labeling treatment polymers. Such tagged treatment polymers are useful as antiscalants in industrial water systems.

Description

Background of the invention [0001] The present invention generally relates to fluorescent monomers. In another aspect, the invention relates to tagging polymers containing these fluorescent monomers. In a further aspect, the present invention relates to the use of a tagged treatment polymer in which a fluorescent monomer is contained in an industrial water system. [0002] In many industrial water systems employing polymers as water treatment agents, it may be desirable to tag or label such polymers to facilitate their monitoring. The term "monitoring" means herein any type of tracking or tracking for determining the position or path of a polymer, as well as any type of determination of the concentration or amount of polymer at any given location, including single or intermittent or continuous monitoring. For example, it may be desirable to monitor water treatment polymers in water systems, or to monitor polymers that may be present in waste fluids prior to disposal, or to ...
