Xylitol-based polyesters such as poly(xylitol sebacate) PXS are said to be the potential new materials for tissue engineering due to their adjustable mechanical and degradation properties. However, the result indicates that the elastomers are very soft and have a low elongation at break. Therefore, to increase the mechanical strength and minimize the rate of degradation, 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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
