Abstract
A new synthetic pathway for the polymerization of furan based polyesters is reported in this work. First, poly(butylene 2,5-furandicarboxylate) cyclic oligoesters (COEs) are chemically synthesized by semi-batch esterification. The structure of the COEs is confirmed by infrared spectroscopy, 1H, and 13C-NMR, while the molecular weight distribution of the COEs is determined by matrix-assisted laser desorption/ionization time of flight mass spectroscopy. The cyclic oligoesters are then successfully polymerized via ring-opening polymerization using tetrakis(2-ethylhexyl)-titanate as catalyst. Differential scanning calorimetry and 1H-NMR analysis unambiguously proves the formation of polymeric species. Both end-group analysis from 1H-NMR spectrum and calculation through Flory–Fox equation give comparable estimates of the number average molecular weight: 5.8 × 103 g mol−1 and 7.8 × 103 g mol−1, respectively.
