    • One reviewer of this manuscript suggested that THF may be an inappropriate choice of solvent for the control experiments in which TFEMA is polymerized in homogeneous solution. This is because this solvent is known to be susceptible to the gradual build-up of appreciable peroxide levels over time. In addition, others have shown that use of THF as a solvent for certain RAFT syntheses can result in significant oxidative degradation of the RAFT chain-ends (see

    • However, we used a fresh bottle of THF (99.8% purity) for all solution polymerizations, which should minimize this problem. Moreover, the above earlier study focused on a dithiobenzoate-based RAFT agent, whereas our work involved a trithiocarbonate-based RAFT agent, which is usually considered to be more stable. Finally, similar changes in UV-visible absorption spectra to those shown in Fig. 7 were also observed when using DMF instead of THF (data not shown), which suggests that the enhanced RAFT chain-end degradation found for the solution polymerizations described herein is not simply due to the peroxide levels in the latter solvent
