Abstract
AbstractSummary: The polymerization of ε‐caprolactone (CL) in the presence of HCl · Et2O by an activated monomer mechanism was performed to synthesize diblock or triblock copolymers composed of poly(ethylene glycol) (PEG) and poly(ε‐caprolactone) (PCL). The obtained PCLs had molecular weights close to the theoretical values calculated from the CL to PEG molar ratios and exibited monomodal GPC curves. We successfully prepared PEG and PCL block copolymers by a metal‐free method.The non‐metal catalyzed living ring‐opening polymerisation of ε‐caprolactone by PEG.magnified imageThe non‐metal catalyzed living ring‐opening polymerisation of ε‐caprolactone by PEG.
