E. Gubbels, L. Jasinska-Walc and C. E. Koning Synthesis and characterization of novel renewable polyesters based on 2,5-furandicarboxylic acid and 2,3-butanediol Journal of Polymer Science Part A: Polymer Chemistry 51
Fully bio-based polyesters were synthesized by bulk polycondensation from 2,5-furandicarboxylic acid or dimethyl-2,5-furandicarboxylate and 2,3-butanediol using titanium (IV) n-butoxide, tin (IV) ethylhexanoate, or zirconium (IV) butoxide as catalyst. The chemical structure of the synthesized poly(2,3-butylene-2,5-furandicarboxylate)s was elucidated by MALDI-ToF-MS, 1H-NMR, 13C-NMR, FTIR, ESI-ToF-MS, and ESI-Q-ToF-MS-MS, and their thermal properties were studied using differential scanning calorimetry and thermogravimetric analysis. Suitable functionality, molecular weight, and thermal properties can make these polyesters appropriate candidates for coating or hot-fill applications.
