| Abstract: | A flexible polyether-ester,poly(diethylene glycol citrate)(PDGC),was synthesized by diethylene glycol and citric acid.A series of polymers were prepared at different postpolymerisation time and different monomer ratios without using any catalyzer.The prepolymer was characterized by FTIR and the elastomers was determinated by ATR-FTIR、DSC、XRD.Mechanical,hydrolytic degradable as well as hydrophilic properties of PDGC were researched. |
