Fluence Analytics and its academic research partner Tulane PolyRMC collaborated on a peer review article for Macromolecular Reaction Engineering which describes the successful online monitoring of the terpolymerization reaction of acrylamide, sodium acrylate, and styrene sulfonate. The terpolymerization reaction was monitored by coupling a nuclear magnetic resonance (NMR) detector to ACOMP. The NMR detector was included because the UV spectra of the acrylamide and sodium acrylate monomers cannot otherwise be distinguished from each other. This work documents the first time ACOMP was used to monitor and control a terpolymerization reaction. Fluence Analytics plans to continue working with PolyRMC to incorporate NMR and other detectors, like FTIR, to enhance ACOMP’s ability to monitor and control copolymers with three or more different comonomers.
