“…Noda et al [25,92] reported the use of 2D Raman spectroscopy in the process monitoring of the emulsion copolymerization reaction of styrene and 1,3-butadiene to produce synthetic rubber latex. Suzuki et al [246] used 2D correlation gel permeation chromatography to characterize the polymerization reaction of silane coupling agent with reactant initial concentration as the perturbation variable.…”
