  1. aCarried out in THF at 60°C for 12 h under nitrogen with a monomer concentration of 0.1 M and catalyst concentration of 0.026 M.
  2. bMwand polydispersity (PDI) of polymers were estimated by GPC in THF on the basis of a PS calibration.
  3. cCopper residue in polymers estimated by atomic absorption spectroscopy (AAS).
