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.en1980-537320073257260ABM [u.a.]https://creativecommons.org/licenses/by-nc/4.0/GlycerolPhthalic acidPolyesterChemieIngenieurwissenschaftenJournal Article10.15480/882.285610.1590/S1516-1439200700030000710.15480/882.2856Journal Article
