Phthalic acid is an aromatic dicarboxylic acid (C 8 H 6 O 2 ) used for the production of polyester such as poly (ethylene terephtalate) (PET) (Guimarães et al., 2007). Polyester, a class of synthetic polymers built up from multiple chemical repeating units linked together by ester (CO-O) groups. The main degradation mechanism of polyesters having high molecular weight is the formation of alkenes, through b-elimination24-27, the trans-esterification and the rearrangements involving the end-groups play also a decisive role on the thermal stability of polyesters28. Polyester resins combine excellent mechanical, electrical and thermal properties with very good chemical resistance and dimensional stability. Isophthalic acid is used as a raw material in the production of polyesters. Although the DSC curves gave no evidences for crystallinity for the POLF polymers, the XRD pattern of POLF III suggest that the presence of rigid aromatic rings, stemmed from the phthalic acid, lead to more rigid structures, which should be more prone to crystallize than fully aliphatic polyesters. Journal of Physical Chemistry C. 2007; 111(6):2803-2808. About 35% of the isophthalic acid is used to prepare unsaturated polyester resins, about 30% is used to produce alkyd coatings, and over 20% is used in other types of polymers, primarily as a minor comonomer with terephthalic acid in saturated polyesters.
