The reversible addition‐fragmentation chain transfer chain length dependent termination (RAFT‐CLD‐T) technique allows a simple experimental approach to obtain chain‐length‐dependent termination rate coefficients as a function of conversion, k t i,i ( x ). This work provides a set of criteria by which accurate k t i,i ( x ) can be obtained using the RAFT‐CLD‐T method. Visualization of three‐dimensional plots varying all kinetic rate parameters and starting concentrations demonstrates that only certain combinations give an accurate extraction of k t i,i ( x ). The current study provides hands‐on guidelines for experimentalists applying the RAFT‐CLD‐T method.
