摘要：The aim of this paper is to present a synthesis method of poly(epsilon-caprolactone) by the ring opening polymerization of epsilon-caprolactone catalyzed with nontoxic magnesium lactate. The results indicated that Mg(LaC)(2) is a catalyst with moderate activity for the polymerization of epsilon-caprolactone. Effects of the catalyst and reaction temperatures on the microstructure of the epsilon-caprolactone and L-lactide copolymers were investigated by means of (13)C-NMR spectroscopy. An increase in the reaction temperature enhances the role of transesterification and the extent of randomness.
