摘要：

A study was conducted to perform spectroscopic evaluation, thermal, and thermomechanical characterization of poly(glycerol-sebacate) (PGS) with variations in curing temperatures and durations. It was demonstrated that that the degree of crosslinking in the material was dependent on cure temperature and duration of cure. The parameter was inferred from changes in ATR-FTIR spectral data and material elasticity. A separate DSC investigation was conducted, focusing on the pre-polymer with the temperature ramp going up to 200 °C. Step tensile tests were also conducted to determine the equilibrium moduli of the various investigated PGS samples.
