| Abstract | ||||
| Xylitol-based polyesters such as poly(xylitol sebacate) PXS are said to be the potential materials for tissue engineering due to their adjustable mechanical and degradation properties. However, the result indicated that the elastomers are very soft and have a low elongation at break. Therefore, to increase the mechanical strength and minimize the degradation rate, glutamic acid was added as the third monomer into the PXS. Novel Poly (xylitol Sebacate Glutamate) (PXSG) was successfully synthesized through melt polycondensation without using any harsh solvents and catalysts. The mixture was synthesized at 120°C for about 8 hours. Post polymerization process was carried out in the oven at 100 °C for three days to develop the crosslink network formation. Several testing and characterization were conducted to evaluate the effect of glutamic acid concentration in the polymer. From the result, FTIR spectroscopy confirmed the ester bond formation, tensile strength, and Young's modulus increased significantly while the percent of elongation at break and degradation rate decreased as the glutamic acid ratio increased. | ||||
