Preparation, Microstructure and Properties of Biodegradable Aliphatic Polyesters by Using Nontoxic Magnesium Catalysts

摘要：

The aim of this paper is to present a synthesis method of biodegradable aliphatic polyesters by the ring opening polymerization of lactones catalyzed with nontoxic magnesium compound. Poly(DL-lactide-co-ε-caprolactone) copolymers were prepared by the copolymerization of DL-lactide and ε-caprolactone using magnesium octoate as a catalyst. Microstructure and crystallization and thermal properties of the obtained polymers were investigated by NMR, XRD and DSC.
