Abstract

This work demonstrated a successful example of RDRP with CuSO₄·5H₂O as a Cu(II) based catalyst in the presence of a reducing agent. CuSO₄·5H₂O produced a more controllable polymerization compared with the widely used CuBr₂. The mechanism was revealed to be a Cu(0)-mediated RDRP with the in situ generated Cu(0) from CuSO₄·5H₂O as the catalyst. This work may provide an alternative, economical and promising copper(II)-based RDRP catalyst, which would eventually enrich and benefit the RDRP technique.
