✦ Synopsis

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 addition of the initiator to the monomer.

Polymerization of 1-caprolactone had been investigated with cyclopentadienyl sodium as an initiator. The effects of reaction time, temperature, and concentration of the initiator on the yield and molecular weight of the polymer were discussed. It was shown that the high molecular weight of poly(1-ca
