Synthesis and Characterization of Poly(1,4-butylene 2,5-furandicarboxylate-co-isosorbide 2,5-furandicarboxylate)
High molecular weight poly(1,4-butylene 2,5-furandicarboxylate-co-isosorbide 2,5-furandicarboxylate) copolyesters (PBSIF-x) were synthesized via melt-polycondensation of 2,5-furandicarboxylic acid (FDCA), with varying ratios of isosorbide (ISB) and 1,4-butylene glycol (BDO) catalyzed by antimony trioxide (Sb2O3). The PBSIF-x structures were investigated using FTIR and 1H NMR, while the GPC analysis exhibited the copolyesters molecular weights with number average molecular mass (Mn) in the range of 11 079–15 153 g/mol. The DSC results show that PBSIF-x copolyesters have a single glass-transition temperature (Tg) (77.45–110.96 °C), increasing with the increase in ISB content, while TGA analysis demonstrates excellent thermal stability up to 320 °C. From the thermal result, properties of PBSIF-x copolyesters are found to be within the interval of their parent homologues poly(butylene 2,5-furandicarboxylate) (PBF) and poly(isosorbide 2,5-furandicarboxylate) (PIF), which confirms the aromatic/aliphatic blending within the polymer matrix for enhanced polymer stability and performance.
