The mechanism of initiation of e-caprolactone polymerization by stable salts has been investigated. Gel permeation chromatography and ~H-NMR spectroscopy were used for determining the compositions of the reaction mixtures and of the polymers. It was established that the initiation proceeds by additi

## Abstract **Summary:** The polymerization of __ε__‐caprolactone (CL) in the presence of HCl · Et~2~O 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 molec
Caprolactone (-CL) has been mixed with ZnCl 2 at different mol ratios. The resulting complex was characterized through 1 H and 13 C NMR spectroscopy in bulk and in solutions, differential scanning calorimetry (DSC), wide-angle X-ray diffraction (WAXD), and optical microscopy. Ring-opening polymeriza
