Design Criteria for Accurate Measurement of Bimolecular Radical Termination Rate Coefficients via the RAFT-CLD-T Method(a)

摘要

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.
