Synthesis, characterization and morphology of new aliphatic-aromatic copolyesters based on trans-1,3- indanediol

Abstract

In this article we report the study on the synthesis and thermal characterization of a new family of aliphatic/aromatic copolyesters that incorporate pure isomer trans-1,3-indanediol. The aromatic diacid terephthaloyl chloride and aliphatic diols HO–(CH2)n–OH with various methylene lengths have been used as co-monomers. The aliphatic diols employed in this study are 1,3-propanediol, 1,4-butanediol, 1,7-heptanediol and 1,10-decanediol. The relevant properties of the synthesized aliphatic–aromatic copolyesters involve viscosity measurements, IR spectroscopy, thermogravimetric analysis (TGA), differential scanning calorimetry (DSC), X-ray diffraction (XRD) analysis and scanning electron microscopy (SEM). The obtained aliphatic-aromatic copolyesters present thermostable nature and semi-crystalline properties.
