Development of a New Copolymer for Multi-Functional Uses

The use of synthetic polymers for mineral scale control in water treatment applications has progressed over the past 50 years. However, most developments occurred towards the onset of widespread use of synthetic polymers in the water treatment industry. Early polymers comprised of primarily carboxylate functionality such as polyacrylic acids, polymethacrylic acids, and polymaleic acids and their salts.

The 1970s saw the development and use of copolymers that incorporated sulfonation and, separately, non-ionic moieties. This was further advanced in the late 1980s where all three functional types (carboxylate, sulfonate, non-ionic) were combined in a single copolymer in an effort to leverage functionality contribution from each monomer type. Over the past 30+ years, new polymer development has largely been variations upon this theme of the use of these three functionality types where incremental benefits have been realized. However, most of these benefits have largely been defined by the additive suppliers based upon narrow functionality targets without specific thought of formulation and field use implications.

This article discusses a new polymer that has been developed based on industry experience, feedback from field use of incumbent technologies, and intentional structure function design.
