Summary : The application of the terminal copolymerization model to polar modified anionic initiated 1,3‐butadiene/styrene systems in hydrocarbon solvent requires the determination of twelve kinetic model parameters. These include frequency factors (k xY, ∞ ), activation energies (E xY ) and live chain end association numbers (n xY ) for all four possible combinations of live chain end termini and free monomer. The individual determination of all twelve parameters requires an enormous numerical effort and a large number of experiments. A method for estimating parameters with a minimum number of kinetic batch experiments in an industrial environment will be demonstrated.
