The effect of agitation on the semicontinuous emulsion copolymerization of styrene and butyl acrylate was investigated. Both neat monomer addition and preemulsified feed were used. Experiments with and without a chain‐transfer agent were carried out. For neat monomer addition, a mild degree of agitation (≥ 0.1 kW/m 3 ) was required to avoid monomer mass‐transfer limitations, but even a moderate degree of agitation (0.3 kW/m 3 ) was not enough to overcome the CTA mass‐transfer limitations. Agitation was much less critical when preemulsified feeds were used. © 2001 John Wiley & Sons, Inc. J Appl Polym Sci 80: 841–851, 2001
