Abstract：Random terpolymers(P) of L-lactide, glycolide and caprolactone had been prepared by bulk ring-opening copolymerization initiated by stannous octoate under high vacuum. The sttucture and properties had been investigated by 1H NMR, IR， DSC and viscosimetry. The results indicated that the glass transition temperature of P can be controlled by adjusting the monomer ration. The submicron fiber membrane of P can be obtained easily through electrospinning.
