Abstract

BRIOUDE, Michel de Meireles et al. Synthesis and characterization of aliphatic polyesters from glycerol, by-product of biodiesel production, and adipic acid. Mat. Res. [online]. 2007, vol.10, n.4, pp.335-339. ISSN 1516-1439.  http://dx.doi.org/10.1590/S1516-14392007000400003.

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 materials are characterized by globular structure, which may suggest compositional fluctuations throughout the samples.

Keywords : polyester; glycerol; biodiesel.
