The seeded semibatch emulsion terpolymerization of styrene–butadiene–acrylic acid is investigated in a pilot plant scale reactor of 151 L. The effect of the styrene–butadiene ratio (S/BD ratio), amount of tertiary‐dodecyl mercaptan as chain transfer agent (CTA), and two temperature profiles on the kinetics of the process (solids content, styrene conversion, particle size, and acid partitioning), by‐product formation (4‐phenyl cyclohexane, 4‐PCH, and 4‐vinyl cyclohexane, 4‐VCH) and the molar mass distribution of the sol and the fraction of gel are studied.
