A mathematical model for the seeded emulsion copolymerization of styrene, butadiene, and an acidic monomer has been developed. The outputs of the model include monomer conversion, copolymer composition, solids content, average particle size, 4‐PCH and 4‐VCH concentrations, overall molecular weight distribution, gel content, distance between crosslinking points, acid distribution between phases, and amount of inactive polymer in the aqueous phase and its composition. The parameters of the model have been estimated using pilot‐plant data and the model captures well the effect of the process variables on the latex characteristics.
