A novel series of biodegradable polyester were synthesized via esterification of sebacic acid
glycol and glycerol.Fourier transform infrared spectrum (FTIR)
X-ray photoelectron spectroscopy (XPS)
Differential scanning calorimetry (DSC)
X-ray diffraction analysis (XRD) and mechanical tests were performed to examine the properties of polyester.Results showed that the products exhibited typical high elasticity.As the ratio of sebacic acid and glycol in raw material increased
the modulus of the products also increased and the microstructure changed from partly order to disorder.The products had good biodegradability
and the weight losses were between 6.1-14.4% after degradation in the phosphate buffer solution with porcine pancreas lipase at 37℃ for 72h.
