Synthesis and characterization of aliphatic polyesters from glycerol, by-product of biodiesel production, and adipic acid
Materials Research 4 (10): 335-339 (2007)
In the present work, polyesters were prepared from the polycondensation between glycerol and adipic acid using dibutyltin dilaurate as catalyst. Three glycerol: adipic acid molar ratio were used for the bulk polymerization namely: 2:2; 2:3 and 2:4. FTIR confirmed the esterification of glycerol by the acid for all the polymers, DSC and XRD indicated no crystallinity for all the polymers. The morphology of the material are characterized by globular structure, which may suggest compositional fluctuations throughout the samples.
