GUIMARAES, Danilo Hansen et al. Synthesis and characterization of polyesters derived from glycerol and phthalic acid. Mat. Res. [online]. 2007, vol.10, n.3, pp.257-260. ISSN 1516-1439.

The production of polyester via polycondensation between glycerol and phthalic acid using dibutyltin dilaurate is reported. Three glycerol:phthalic acid molar ratio used for the bulk polymerization were: 2:2; 2:3 and 2:4. FTIR confirmed the esterification of glycerol by the acid for all the polymers. DSC indicated no crystallinity, although the XRD plots indicate a very incipient crystallinity for the polymers containing higher amounts of phthalic anhydride. Scanning electron microscopy results indicates high homogeneity for all the polymers prepared.

Keywords : polyester; glycerol; phthalic acid.
