AbstractThe kinetics of the ferric ethylenediaminetetraacetate (EDTA)–diisopropylbenzene hydroperoxide (DIBHP)‐sodium formaldehyde sulfoxylate (SFS) redox system were determined. The rate constant is a function of the ionic strength μ. A plot of log10(rate constant), for the rate‐limiting second‐order iron—SFS reaction, vs.μ1/2has a slope of 1.3 with a limiting rate constant of 295 ± 15 L. mol−1. min−1at μ = 0. The slope of this plot decreases to essentially zero for μ>0.06M. Incorporation of these results into the Smith‐Ewart model for emulsion polymerization correctly predicts the dependence of latex particle size on Fe and DIBHP concentration, but a much lower dependence on SFS conce
